Read each question carefully and provide concise answers. Show all your work for calculation-based problems.
1. Which of the following statements best defines impulse?
The rate of change of momentum.
The change in momentum of an object.
The force applied to an object over a distance.
The product of mass and velocity.
2. What is the SI unit for impulse?
Newton (N)
Joule (J)
Newton-second (N·s)
Watt (W)
1. Impulse is equal to the change in an object's .
2. When a constant force acts on an object, the impulse is the product of the force and the over which it acts.
1. Explain the relationship between impulse and force. How can a small force produce a large impulse?
2. A baseball of mass 0.15 kg is pitched at 40 m/s. The batter hits it back toward the pitcher at 60 m/s. If the bat is in contact with the ball for 0.002 seconds, calculate the impulse exerted on the baseball. Show your work.
1. A larger impulse always results in a larger change in velocity.
True
False
2. Airbags in cars increase the impulse during a collision.
True
False
Match each term with its correct definition or description.
1. Momentum
a. The product of force and time.
2. Impulse
b. A vector quantity that is the product of an object's mass and velocity.
3. Impulse-Momentum Theorem
c. States that the impulse acting on an object is equal to the change in its momentum.
Consider a scenario where a car crashes into a rigid wall versus crashing into a deformable barrier (like a stack of tires). Using your understanding of impulse, explain why the deformable barrier is safer for the occupants of the car.
