Motorcycle safety helmet extend the time of collision hence decreasing the:
Correct answer: C. Force acting
- A. Chance of collision
- B. Velocity
- C. Force acting
- D. Imuplse
Explanation
The average force generated in a collision is equal to the momentum change during the collision divided by the time interval in which collision is taken place. The pad inside the helmet extends the time interval over which the collision occurs and reduces the force experienced by the brain during collisions. That is why the safety helmet of a motorcycle's is padded.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
