Question

As the block slides down the incline, the sum of its gravitational potential energy with respect to the horizontal and kinetic energyA. DecreasesB. IncreasesD. Stays the same

Answer 1

D. Stays the same

Step-by-step explanation:

When a block slides down the incline, the potential energy will drecrease because it depends on the height and the kinetic energy will increase because it depens on the speed. However by the conservation of energy, the sum of these energies will be constant.

It means that the answer is

D. Stays the same
