Question

unit 1b test

impulse is

• the time it takes for an object to stop
• mass x velocity
• change in momentum
• a push or pull

Explanation:

Step1: Define impulse

Impulse is the product of the average force applied to an object and the time interval over which it acts.

$$J = F \cdot \Delta t$$

Step2: Relate impulse to momentum

According to the impulse-momentum theorem, impulse equals the change in momentum.

$$J = \Delta p$$

Answer:

C. change in momentum
