Force and Motion
Interactions
Gravity
Enduring Understanding
(Generalizations)
Nothing in the universe is at rest. Motion is
as essential to understanding the physical
world as matter and energy are. All motion
is relative. All motion is governed by the
same basic rules.
Gravity is an attractive interaction. The
earth's gravity pulls any object on or near the
earth toward it without touching it. A
gravitational field is caused by an object with
mass.
Changes in speed or direction of motion
are caused by forces. The greater the force is,
the greater the change in motion will be. The
more massive an object is, the less effect a
given force will have.
The motion of an object can be described
by its position, direction, motion and speed.

the relationship between them.
5.P.1.1 Explain how factors such as gravity, friction, and
change in mass affect the motion of objects.
5.P.1.2 Infer the motion of objects in terms of how far
they travel in a certain amount of time and the direction
in which they travel.

show a change in position over a period of time.
5.P.1.4 Predict the effect of a given force or a change in

Essential Questions
(Guiding Questions)
What is the origin of motion?
How are motion and gravity
connected?
What is gravity? How does gravity
‘work’?
How are gravity and mass connected?
How are force and motion connected?
How can we describe their relationship?
How can we model the relationship of
position, motion, direction and speed?
Motion can be measured and represented on
a graph.
Essential Terminology: WAKE COUNTY
acceleration: rate of increase of speed or velocity (example: accelerator pedal on a car)
air resistance (drag): force of air pushing against the motion of an object
balanced force: an object remains in place, no movement occurs
control: part of an experiment that does not change, serves as the standard to compare other observations
direction: the way the force is applied determines this way an object moves
energy: ability to do work
energy, kinetic: energy of motion (moving ball going down a ramp)
energy, potential: stored energy (ball positioned at the top of the ramp)
fair test: changing only one variable and keeping the other conditions the same
force: any push or pull on an object
friction: force that resists motion between two touching surfaces, slows things down and can also produce heat, acts in the opposite
direction of the force
gravity, gravitational force: force that brings objects toward earth
inertia: the tendency of an object to resist a change in motion or keep doing what it is doing
Note: the greater the mass of an object, the greater the inertia
mass: how much matter an object contains
momentum: force or speed of movement; mass in motion, example: a moving train has much more than a moving soccer ball
Note: momentum = mass of an object x velocity
(increasing the mass or speed increases the momentum)
motion: an object changing position over time; change in position is measured by distance and time
Newton’s 1st law of motion: *An object tends to stay at rest and an object tends to stay in motion with the same speed and in the same
direction unless acted on by an unbalanced force.
* Objects tend to keep doing what they are doing.
* If the forces acting upon an object are balanced, the acceleration of that object will be zero (no motion).
*also known as the “law of inertia”
Newton’s 2nd law of motion: * Acceleration is always in the direction of the unbalanced force.
*If you want something to accelerate faster, you need to decrease its mass.
* Acceleration of an object depends upon two variables—the net force acting upon the object and the mass of the object.
* Force = mass x acceleration or F = ma
Newton’s 3rd law of motion: *Explains why forces act in pairs.
* For every action, there is an equal and opposite reaction.
* When one object exerts a force on a second object, the second object exerts the same amount of force back on the first object (but in the
opposite direction).
* Equal forces acting in opposite directions create a net force of zero.
* Action and reaction forces are equal forces acting in opposite directions. The reason they can’t cancel each other out is because they are
acting on different objects.
propeller: two or more twisted blades that rotate around a central point or shaft (shaft: pipe or tube)
recursive: consequential steps
resistance: force pushing against the motion of an object
speed (rate): distance divided by time (or d/t), example: 25 mph
unbalanced force: motion occurs; the movement goes in the direction of the greater force (example: winning a tug-of-war game)
validity: conducting a fair test
variable: something in an experiment that can be changed
velocity: speed with direction (ex.: 45 mph NW)
weight: force of gravity pulling down on an object
work: moving an object over a distance

Unpacked Content
5.P.1.1
Students know that gravity pulls any object on
or near the earth toward it without touching it.
Students know that friction is a force that is
created anytime two surfaces move or try to
move across each other. Students know that all
matter has mass. Students understand that
changing any or all of these factors will affect
the motion of an object.
5.P.1.2
Students know that it is possible to measure
the motion of an object based on the distance it
will travel in a certain amount of time.
5.P.1.3
Students know that a graph can be created
using one axis to represent the distance that an
object travels, and the other axis to represent
Science For All Americans
Motion is as much a part of the physical world as matter
and energy are. Everything moves—atoms and molecules; the
stars, planets, and moons; the earth and its surface and
everything on its surface; all living things, and every part of
living things. Nothing in the universe is at rest.
Since everything is moving, there is no fixed reference
point against which the motion of things can be described. All
motion is relative to whatever point or object we choose.
Thus, a parked bus has no motion with reference to the
earth's surface; but since the earth spins on its axis, the bus is
moving about 1,000 miles per hour around the center of the
earth. If the bus is moving down the highway, then a person
walking up the aisle of the bus has one speed with reference
to the bus, another with respect to the highway, and yet
another with respect to the earth's center. There is no point in
space that can serve as a reference for what is actually

the period of time the object is traveling.
Students know how to construct a graph that
demonstrates a relation of distance to time.
5.P.1.4
Students know that the greater a force is, the
greater the change (in motion) it produces. The
greater the mass of the object being acted on,
the less the effect of the (same) force.
moving.
Changes in motion—speeding up, slowing down, changing
direction—are due to the effects of forces. Any object
maintains a constant speed and direction of motion unless an
unbalanced outside force acts on it. When an unbalanced
force does act on an object, the object's motion changes.
Depending on the direction of the force relative to the
direction of motion, the object may change its speed (a falling
apple) or its direction of motion (the moon in its curved
orbit), or both (a fly ball).
The greater the amount of the unbalanced force, the more
rapidly a given object's speed or direction of motion changes;
the more massive an object is, the less rapidly its speed or
direction changes in response to any given force. And
whenever some thing A exerts a force on some thing B, B
exerts an equally strong force back on A. For example, iron
nail A pulls on magnet B with the same amount of force as
magnet B pulls on iron nail A—but in the opposite direction.
In most familiar situations, friction between surfaces brings
forces into play that complicate the description of motion,
although the basic principles still apply.
Everything in the universe exerts gravitational forces on
everything else, although the effects are readily noticeable
only when at least one very large mass is involved (such as a
star or planet). Gravity is the force behind the fall of rain, the
power of rivers, the pulse of tides; it pulls the matter of
planets and stars toward their centers to form spheres, holds
planets in orbit, and gathers cosmic dust together to form
stars. Gravitational forces are thought of as involving a
gravitational field that affects space around any mass. The
strength of the field around an object is proportional to its
mass and diminishes with distance from its center. For
example, the earth's pull on an individual will depend on
whether the person is, say, on the beach or far out in space.
