What happens to the force of impact when you double your speed?

It doubles
It increases by four times
It triples
It decreases

The correct answer is: It increases by four times

Doubling your speed also means doubling your kinetic energy. The force of impact is the force applied when two objects collide and is related to their kinetic energy. When doubling the speed, the kinetic energy also doubles, resulting in a four times increase in the force of impact. Option A is incorrect because doubling the speed does not simply double the force of impact. Option C is incorrect because it assumes a linear relationship between speed and force, which is not the case. Option D is incorrect because increasing the speed results in an increase, not a decrease, in the force of impact.
