Understanding Impulse and Momentum

What is the key to successfully pushing a straw through a potato?

• Using a cooked potato

• Applying force quickly

• Using a sharp straw

• Applying force slowly

According to Newton's second law, what is force proportional to?

• The distance traveled

• The velocity of an object

• The rate of change of momentum

• The mass of an object

What does the area under a force-time graph represent?

• Impulse

• Velocity

• Acceleration

• Distance

How can you reduce the force experienced by an object during a collision?

• Decrease the collision time

• Increase the collision time

• Increase the object's mass

• Decrease the object's velocity

Why are car airbags designed to increase collision time?

• To increase the force on the driver

• To make the car stop faster

• To decrease the change in momentum

• To reduce the force experienced by the driver
