Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following best describes momentum?
A measure of an object's inertia.
The product of an object's mass and velocity.
The rate of change of an object's position.
The force acting on an object.
2. Impulse is equal to the change in an object's:
Kinetic energy
Acceleration
Momentum
Potential energy
3. The principle of conservation of momentum states that the total momentum of an isolated system remains .
4. When two objects collide and stick together, the collision is said to be perfectly .
5. A 2.0 kg bowling ball moving at 10 m/s strikes a 0.5 kg pin, causing the pin to move forward at 15 m/s. If the bowling ball continues to move in the same direction at 9.0 m/s, what was the initial momentum of the bowling ball?
6. Explain the concept of impulse and how it relates to safety features in cars, such as airbags.
7. In an elastic collision, both momentum and kinetic energy are conserved.
True
False
8. A larger force applied over a shorter time can produce the same impulse as a smaller force applied over a longer time.
True
False
