Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best defines momentum?
The force an object exerts
The mass of an object multiplied by its velocity
The rate at which an object changes its position
The energy an object possesses due to its motion
2. In an inelastic collision,
kinetic energy is conserved
momentum is not conserved
objects stick together after impact
both kinetic energy and momentum are conserved
3. The principle of states that the total momentum of a closed system remains constant.
4. Impulse is defined as the change in . It is also equal to the applied over a time interval.
5. A 2 kg ball moving at 5 m/s collides with a 3 kg ball at rest. If they stick together after the collision, what is their combined velocity?
6. In an elastic collision, objects deform and generate heat.
True
False
7. A larger impulse can be achieved by applying a smaller force over a longer time.
True
False
8. Observe the image below. Describe how the concept of impulse is relevant in designing safety features for vehicles involved in collisions.
Match the term on the left with its definition on the right.
9. Momentum
a. Product of force and time interval
10. Impulse
b. Collision where kinetic energy is conserved
11. Elastic Collision
c. Product of mass and velocity
12. Inelastic Collision
d. Collision where objects stick together
