Since the penny was up and stationary before (in your hand or wherever), it had potential energy at first. When it's dropped, it is converted into kinetic energy (energy of motion).
As the penny falls toward the ground, potential energy is converted to kinetic energy. Potential energy is stored energy based on an object's position or shape, while kinetic energy is the energy of motion.
When an apple falls from a tree, its potential energy from being high up in the tree is converted to kinetic energy as it accelerates toward the ground. This conversion of potential energy to kinetic energy illustrates the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred from one form to another.
An atomic bomb is usually dropped from an aircraft before detonation. The bomb is released from the aircraft, allowing it to fall toward the target area where it explodes upon impact with the ground.
The force that pushes everything to the ground is gravity. Gravity is the force of attraction between two objects with mass, pulling them toward each other. It is what gives objects weight and causes them to fall to the ground when dropped.
This is actually two questions. Energy relating to the motion of an object is kinetic energy. Energy related to its position is potential energy (as with a brick suspended at some distance above the ground). Release the brick and its potential energy is converted to kinetic energy. The two are complementary. As the brick accelerates toward the ground its kinetic energy increases; as the distance decreases during that acceleration, it's potential energy decreases.

Potential - Kinetic - Potiential again as you drop the yo yo, the potential energy it had at its height is converted to kinetic energy. as it starts to come back up, it is converted back to potential energy

The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
The bowling ball has both kinetic and potential energy as it rolls towards the pins. The kinetic energy comes from its motion, while the potential energy comes from its position relative to the ground.
Calculate the gravitational potential energy between 5 m and 2 m above the ground. If you ignore air resistance, all of that potential energy will be converted to kinetic energy, so that's the answer.
