Matter and Forces in Motion (2a-2c)
REVIEW
1. If you ride your bicycle down a straight road for 500 m then turn around and ride back, your distance is
greater than your displacement.
2. Motion is a change in position.
3. The speed you read on a speedometer is instantaneous speed.
4. 3 m/s north is an example of a(n) velocity.
5. The relationship among speed, distance, and time is s = d/t.
6. A single point on a distance-time graph tells the instantaneous speed.
7. A merry-go-round horse moves at a constant speed but at a changing velocity.
8. Acceleration is rate of change of velocity.
9. If you ride your bike up a hill, then ride down the other side, your acceleration is first negative, then
positive.
10. The equation used to find acceleration is a = vf – vi/t
11. A horizontal line on a velocity/time graph shows zero acceleration.
12. Inertia varies depending on mass.
13. Newton's first law of motion is also called the law of inertia.
14. The upward force on an object falling through the air is air resistance.
15. The relationship among mass, force, and acceleration is explained by Newton’s second law of motion.
16. A feather will fall through the air more slowly than a brick because of air resistance.
17. In the absence of air, a penny and a feather that are dropped from the same height at the same time will fall
at the same rate.
18. The acceleration due to gravity is 9.8m/s2

19. According to Newton's second law of motion, F = m x a
20. When an object moves in a circular path, it accelerates toward the center of the circle as a result
of centripetal force.
21. The path of a projectile is curved.
22. For any object, the greater the force that's applied to it, the greater its acceleration will be.
23. The size of the gravitational force between two objects depends on their masses and distance between
them.
24.As you get farther from the center of Earth, your weight will decrease.
25.When a force is exerted on a box, an equal and opposite force is exerted by the box. These forces are called
action-reaction forces.
26.A real car moving at 10 km/h has more momentum than a toy car moving at the same speed because the real
car has greater mass
27.In the equation p = m v, the p represents momentum.
28.The statement "to every action there is an equal and opposite reaction" is Newton’s third law of motion.
29.The unit of momentum is kg x m/s
30.When two balls collide, the momentum of the balls after the collision is explained by the law of
conservation of momentum.
