Potential and Kinetic Energy 2 P

Front

What is Kinetic Energy?

Back

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

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground and is calculated using the formula PE = mgh.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass; if two objects are moving at the same speed, the one with greater mass will have more kinetic energy.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the velocity; if the speed of an object doubles, its kinetic energy increases by a factor of four.

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 air resistance.

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy increases as the height of an object increases, since it is directly proportional to height (PE = mgh).

Front

What is the unit for height?

Back

The unit for height is meters (m).
