Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is often associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy is directly proportional to the square of the speed. This means that if the speed of an object doubles, its kinetic energy increases by a factor of four.

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the mass of the object, the height of the object above a reference point, and the acceleration due to gravity.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object. If the mass increases while the speed remains constant, the kinetic energy increases.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy is KE = 1/2 mv².

Front

What is the formula for calculating Potential Energy?

Back

The formula for calculating Potential Energy is PE = mgh.

Front

Why do objects at higher elevations have more Potential Energy?

Back

Objects at higher elevations have more Potential Energy because they have the potential to fall a greater distance due to gravity.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

How can you increase the Potential Energy of an object?

Back

You can increase the Potential Energy of an object by increasing its height or mass.
