Lesson 1 How do Forces Affect Motion
____________________ - A push or a pull on an object that can cause it to change
direction.
______________________ moves, stops, or changes direction without
______________________.
Heaver objects ______________________________________________
_________________________________________________________.
_____________________________ - a force that pulls two objects toward each
other because of their mass, such as you toward the center of the earth.
Mass – a measurement of the amount of material (matter) that makes up an
object.
Weight - is a measurement of how hard the earth’s gravity pulls on an object.
The more mass an object has the more it ________________________.
More ____________ = More _____________ = More ______________
Everything with mass has a gravitational pull.
You have mass therefore you have ___________________.
Do you have a lot of it? _______
Who is this guy?
_________________________________________________________
Tell 2 cool things he did


 He discovered that objects will continue moving in a straight line until a force
causes it to slow down or stop.
 He also discovered that an object not moving, or at rest, will stay at rest until
a force, such as a push or a pull, moves it.
 This is called inertia, and is Newton’s 1st law of motion (He has 3)
_________________________ -The tendency of a moving object to stay in motion
or resting object to stay at rest.
So when I kicked the soccer ball it went for ever right? ____________
What slowed it down and made it stop? _______________________
__________________________- is a force that slows down the motion of moving
object.
Name 2 things an object can have friction with.

________________________ - The ability to do work.
_____________________________ - The energy that an object has because of its
position.
Types of potential energy include:
 Sitting at the top of a slide
 At the highest point on a swing
 _____________________________________________
 _____________________________________________
 _____________________________________________
 _____________________________________________
___________________________ - The energy of motion
Types of kinetic energy include:
 Going down the slide
 Moving on the slide
 __________________________________________________
 __________________________________________________
 __________________________________________________

Other Forms of Energy
___________________________ - The kind of energy an object has because it can
move or because it is moving.
Mechanical Energy can be potential or kinetic energy.
___________________________ - the energy that comes from chemical change.
Chemical energy is a type of potential energy.
Types of chemical energy include:
 A battery (not in anything)
 Gasoline (in a can)
 ______________________________________________
 ______________________________________________
____________________________ - The energy that comes from the flow of
electricity.

__________________________ - the result of a force moving an object.
When you push or pull something and it moves you have done work.
The amount of work you do depends on how much force you use and how far the
object moves.
If you push or pull on an object really hard and it does not move, then you have
not done work.
_______________________________ - a machine made of one or two parts.
Simple machines make work easier.
Type of simple machine
Definition
a flat surface with one
side higher than the other
(ramp)
Wheel and Axel
A simple machine with
slanted sides
Lever
A lever is a stiff bar that
rests on a support called a
fulcrum which lifts or
moves loads
Picture
A Simple machine that
uses a rope and a wheel
to move an object
Screw
An incline plane wrapped
around a rod.
______________________________ - a machine made of two or more simple
machine.
Label the different simple machines in this compound machine.
_________________________ - a machine made up of many compound and
complex machines.
 Like a car, truck, plane, or tractor
