The video explores how helmets affect impulse and impact force during collisions. Initially, a medicine ball without a helmet is dropped, and its impact force and impulse are measured. The impulse equation is explained, highlighting the relationship between force, momentum, and time. Adding a helmet increases the collision time, reducing the impact force but slightly increasing the impulse due to a higher rebound velocity. The experiment demonstrates that helmets can reduce the force experienced during impacts, emphasizing their protective role.

What was the maximum force of impact measured when the medicine ball was dropped without a helmet?

• 971 newtons

• 544 newtons

• 1,310 newtons

• 618 newtons

Which equation represents the concept of impulse in physics?

• Impulse equals change in momentum

• Impulse equals mass times velocity

• Impulse equals force times distance

• Impulse equals energy divided by time

How does adding a helmet affect the time during a collision?

• It increases the time

• It decreases the time

• It keeps the time constant

• It has no effect on time

What was the maximum force of impact when the medicine ball was dropped with a helmet?

• 1,310 newtons

What was the observed effect on the rebound height when the medicine ball was dropped with a helmet?

• The rebound height was lower

• The rebound height was the same

• The rebound height was higher

• The rebound height was unpredictable
