Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. What is the definition of impulse?
A type of energy
The product of force and time
The rate of change of velocity
The amount of work done
2. Which of the following statements about impulse is true?
Impulse is a scalar quantity.
Impulse is equal to the change in momentum.
Impulse has units of Newtons per second.
Impulse only occurs in collisions.
3. Impulse is directly proportional to the applied and the over which it is applied.
4. The unit of impulse is the , which is equivalent to .
5. Explain how airbags in cars help reduce injuries during a collision in terms of impulse and momentum.
6. A tennis player hits a 0.06 kg tennis ball with a force of 50 N. If the racket is in contact with the ball for 0.01 seconds, calculate the impulse imparted to the ball.
7. A larger impulse always results in a larger change in velocity.
True
False
8. The impulse-momentum theorem states that the impulse applied to an object is equal to its change in kinetic energy.
True
False
9. Design an experiment to demonstrate the relationship between impulse and the time of impact. Describe the materials you would use, the procedure, and what results you would expect to observe.
