Kinetic and Potential Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the definition of potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly 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 mass affect kinetic energy?

Back

Increasing an object's mass will increase its kinetic energy, as kinetic energy is directly proportional to mass.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; doubling the speed results in four times the kinetic energy.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is positioned, the greater its potential energy.

Front

What type of energy is associated with a compressed spring?

Back

A compressed spring has elastic potential energy, which is stored energy due to its deformation.

Front

What is the principle of conservation of energy?

Back

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

Front

At what point does an object have maximum potential energy in a gravitational field?

Back

An object has maximum potential energy at its highest point in a gravitational field.

Front

At what point does an object have maximum kinetic energy in a gravitational field?

Back

An object has maximum kinetic energy at its lowest point in a gravitational field, where its speed is greatest.

Front

What is the formula for calculating gravitational potential energy?

Back

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