What is force of impact?

• A. The force due to gravity
• B. The force resisting motion
• C. The force from engine power
• D. The force generated when objects meet

Answer: (D)

The force of impact is the force generated when two objects meet and collide, exchanging momentum over the short time they stay in contact. It’s this abrupt change in motion that creates the collision force. It’s not gravity (a constant downward pull) or the general force that resists motion like friction, and it isn’t engine power. The size of the impact force depends on how much momentum is involved (mass and speed) and how long the contact lasts: quicker, stiffer impacts produce larger forces, while longer or more forgiving contacts (crumple zones, padding) reduce the peak force.
