Potential and Kinetic Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What factors affect the kinetic energy of an object?

Back

The kinetic energy of an object depends on its mass and the square of its velocity.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What are the two main types of potential energy?

Back

The two main types of potential energy are gravitational potential energy and elastic potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground and its mass.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect gravitational potential energy?

Back

As the height of an object increases, its gravitational potential energy increases.

Front

What is the relationship between potential energy and kinetic energy in a closed system?

Back

In a closed system, the total mechanical energy (potential energy + kinetic energy) remains constant.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is associated with electromagnetic radiation.
