Best answer BRAINLIEST!

A box is released from rest and slides down a ramp in a closed system. Even though the box speeds up, its kinetic energy at the bottom of the ramp is less than the potential energy that it had at the top of the ramp.

What best explains why the box’s final kinetic energy is less than its initial potential energy?

a) In a closed system, kinetic energy is always less than potential energy.
b) Some potential energy was converted into thermal energy due to friction.
c) The acceleration due to gravity became smaller as the box slid down the ramp.
d) In a closed system, total energy is constantly being lost to outside objects.

Respuesta :

Answer:

As the box slides down the ramp, its potential energy decreases

and, if there's not too much friction, its kinetic energy increases.

c

Explanation:

The acceleration due to gravity became smaller as the box slid down the ramp.

Why is kinetic energy less than potential power?

The sum of an object's ability and kinetic energies is referred to as the object's mechanical electricity. As an object falls its capacity energy decreases, while its kinetic strength increases. The lower in ability power is precisely identical to the increase in kinetic strength.

Is initial kinetic energy equal to final potential energy?

Proper before it hits the ground, the initial capability power and the final kinetic power will same every other because of the conservation of power. If we resolve for initial ability, we can discover the final kinetic power.
