Energy Concepts Practice (#2)

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its position in a gravitational field, typically related to its height above the ground.

Front

What is spring potential energy?

Back

Spring potential energy is the energy stored in a compressed or stretched spring, which can be released to do work.

Front

How is mechanical energy defined?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

What happens to energy in a closed system?

Back

In a closed system, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is the principle of energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from potential energy to kinetic energy.

Front

What role does friction play in energy transfer?

Back

Friction converts kinetic energy into thermal energy, causing moving objects to eventually stop.

Front

What is the relationship between energy and work?

Back

Work is done when energy is transferred from one system to another, often resulting in movement.

Front

What happens to energy when a soccer ball is kicked?

Back

When a soccer ball is kicked, energy is transferred from the foot to the ball, causing it to move.

Front

What is elastic energy?

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched, such as in a spring or a drawn bow.
