A because it requires energy from food to move which is mechanical
Answer:
energy is being used to make or break bonds between molecules
Explanation:
if correct please consider brainliest
Answer:
Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless
ramp is equal to the gravitational potential energy of the block at the top of the ramp. This
value is proportional to the square of the block’s velocity at the bottom of the ramp.
Therefore, the block’s final velocity depends on the height of the ramp but not the steepness
of the ramp
