Impulse and Momentum Quiz

What is the primary purpose of using impulse in physics?

• To decrease an object's volume

• To alter an object's momentum

• To increase an object's mass

• To change an object's energy

When a ball bounces off a wall, why is it important to consider direction in calculating velocity change?

• Because direction affects the mass

• Because direction affects the force

• Because direction affects the time

• Because direction affects the velocity change
