Why is it difficult to use the law of conservation of energy to calculate the effects of a collision?

B

Explanation:

In a collision some of the kinetic energy of the object convert into thermal energy and sound. It's not so easy to measure thermal and sound energy. That's why it's difficult to use law of conservation of energy.

Alert: Energy is always conserved.

Energy is converted to heat during a collision.

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
