Potential and Kinetic Energy

Front

What type of energy is associated with an object in motion?

Back

Kinetic Energy

Front

What type of energy is stored in an object due to its position or state?

Back

Potential Energy

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 acceleration due to gravity, and h is height.

Front

How does the kinetic energy of an object change if its speed doubles?

Back

The kinetic energy increases by a factor of four (since KE is proportional to the square of the velocity).

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases, assuming no energy is lost to friction.

Front

At what point on a roller coaster is the potential energy the highest?

Back

At the top of a big hill.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, an object can have both types of energy simultaneously, such as a roller coaster at the top of a hill just before it descends.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band or a book on a shelf.
