Kinetic and Potential Energy

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 the square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is the formula for 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 the formula for 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 mass affect Kinetic Energy?

Back

The greater the mass of an object, the greater its Kinetic Energy, assuming the velocity remains constant.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the velocity; if the velocity doubles, the Kinetic Energy increases by a factor of four.

Front

What unit is used to measure energy?

Back

Energy is measured in Joules (J).

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height and mass of the object.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases, assuming no energy is lost to friction.

Front

What is the relationship between Kinetic and Potential Energy in a closed system?

Back

In a closed system, the total energy (Kinetic + Potential) remains constant, demonstrating the principle of conservation of energy.
