Resultants
Inertia
Newton’s 1st Law of Motion (law of
inertia)
Mass
Weight
g is the rate of acceleration due to
gravity (9.8 m/s2)
Weight equation
w = mg
Types of Forces
Normal Force (sometimes called
support force)
Gravity (also called weight)
Applied Force
Tension
Spring Force
Friction
Air Resistance (also called drag)
Force SI Unit: Newtons
Aristotle, Galileo and Newton
Newton’s 2nd Law of Motion
(Fnet = ma)
Inverse and direct relationships
Newton’s 3rd Law of Motion
(Action Force = Reaction Force)
Action-Reaction Pairs
A net force external to the system is
needed for acceleration
Essential Questions
1. How do various forces influence the motion of an object?
2. What is gravity's role in the interaction of matter?
3. How can Newton’s laws of motion be used to understand and
predict the motion of objects?
Learning Targets
LT 1
I can explain force, and identify the seven different types of forces.
LT 2
I can describe the three possible states of motion for an object, and the
causes for acceleration and constant velocity.
Lt 3
I can explain the difference between balanced and unbalanced forces,
and the relationship to net force and changes in motion.
LT 4
I can generate free-body diagrams showing force interactions.
LT 5
I can explain how friction (and air resistance) influence motion, and how
kinetic and static friction differ.
LT 6
I can state each of Newton’s three laws of motion and give an example of
each.
LT 7
I can describe inertia and its relationship to the 1st law of motion, and how
Galileo’s and Newton’s view of motion differed from Aristotle’s.
LT 8
I can explain and calculate the difference between mass and weight.
LT 9
I can explain the difference between force and pressure.
LT 10 I can explain how Newton’s 2nd law of motion is used to describe the
relationships between force, acceleration and mass.
LT 11
I can use Newton’s 2nd law of motion to solve problems.
LT 12 I can explain how Newton’s 3rd law expresses force interactions between
objects and its significance to motion.
LT 13
I can apply Newton’s Laws of Motion to the movement and changes in
movement of objects.
