β 14y agoSince 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).

β 14y agoAs a dropped penny falls toward the ground, potential energy is converted into kinetic energy. The higher the penny is dropped from, the more potential energy it has, which is converted into kinetic energy as it accelerates downwards due to gravity.
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.
The kinetic energy is associated with the motion of an object due to its velocity, while potential energy is associated with the position of an object in a force field (gravitational, electrical, etc.). Each type of energy can be converted into the other under specific conditions.

When dropping a yo-yo, potential energy is converted into kinetic energy as the yo-yo falls. The potential energy from gravity pulling the yo-yo downward is transformed into the motion energy of the yo-yo as it accelerates toward the ground.
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.

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.
At 5 m above the ground, the weight's potential energy is given by PE = mgh = 20 kg x 9.8 m/s^2 x 5 m = 980 J. When the weight is 2 m above the ground, its potential energy is now PE = 20 kg x 9.8 m/s^2 x 2 m = 392 J. The difference in potential energy between the two points is the kinetic energy the weight has at 2 m above the ground, which is KE = 980 J - 392 J = 588 J.
Gravity transforms energy by converting potential energy into kinetic energy as objects fall towards the center of a gravitational field. The potential energy stored in an object due to its position relative to a gravitational source is converted into kinetic energy as the object moves toward that source.
