What type of energy does this picture represent?

• Potential energy is transferred from the boy's foot to the ball.

• Kinetic energy is transferred from the boy's foot to the ball.

This energy is a fundamental concept in physics that quantifies the work performed by an object due to its motion.

• potential energy

• kinetic energy

• gravitational energy

• sound energy

In simple terms, this energy comes from vibrations / waves moving through something.

• temperature

• kinetic energy

• sound energy

• potential energy

This energy is type of stored energy that an object or system of objects may have based on their size, shape, position, or even material they are made from.

• potential energy

• kinetic energy

• energy from atoms

• nuclear energy

Energy is passed on or wasted, but never lost, when an object wastes energy, then another object gains the energy (usually heat).

• True

• False
