Essential Concepts and Skills
Newton’s Laws Of Motion(PS. 10 b)
o Newton’s Three Laws of Motion describe the motion of all common
objects.
 Identify situations that illustrate each Law of Motion
 Newton’s First Law: An object in motion/rest will remain in
motion/rest unless acted upon by and outside force.
 Newton’s Second Law: The amount of acceleration depends on
the size of the force and mass.
*FORCE = MASS x ACCELERATION
 Newton’s Third Law: For every action force there is an equal and
opposite reaction .
 Law of Conservation of Momentum: In any collision, the total
amount of momentum does not change (momentum before =
momentum after).
*MOMENTUM = MASS x VELOCITY

LAWS OF MOTION & MOMENTUM STUDY GUIDE
FIRST LAW
1.
2.
3.
4.
State the first law of motion.
What factor affects the inertia of an object?
If inertia is increased, an object will tend to …..
Compare the inertia of two objects, each with a different mass.
SECOND LAW
5. Name the two factors that affect acceleration.
6. List two ways that acceleration can be decreased.
7. Use the second law to explain why objects accelerate towards the ground at the same
rate. (when in a vacuum)
8. What force is needed to accelerate a 250 kg object 5 m/s/s?
THIRD LAW
9. State the third law of motion.
10. Explain the third law of motion by using an everyday application.
11. If action-reaction force pairs are equal in size, opposite in direction, why don’t they
cancel each other?
12. Using the game of pool, identify action-reaction forces.
MOMENTUM
13. Identify two ways that momentum can be increased.
14. Relate the conservation of momentum to a game or sport you enjoy.
15. Compare the momentum before and after a collision.
