Kinetic and Potential Energy Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as 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 height, commonly calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect potential energy?

Back

As the height of an object increases, its potential energy increases because it has the potential to do more work due to its elevated position.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is directly proportional to the square of the velocity; if the velocity doubles, the kinetic energy increases by a factor of four.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and the square of its velocity.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as PE = mgh.

Front

How can potential energy be converted to kinetic energy?

Back

Potential energy can be converted to kinetic energy when an object falls or moves downward, as it loses height and gains speed.

Front

What is the formula for calculating kinetic energy?

Back

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