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 stored energy of an object due to its position or state. It can be gravitational potential energy (GPE) or elastic potential energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy (GPE) is the energy an object has due to its height above the ground. It is calculated using the formula GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Where is gravitational potential energy minimum?

Back

Gravitational potential energy is minimum at the lowest point, such as down in the basement.

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height and mass of the object.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy is calculated using the formula KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What is the Kinetic Energy of a 0.145 kg baseball thrown at 30.0 m/s?

Back

The Kinetic Energy is 65.25 J, calculated using KE = 1/2 mv².

Front

What type of energy is stored in a stretched rubber band?

Back

The energy stored in a stretched rubber band is Potential Energy.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).

Front

What happens to Kinetic Energy if the velocity of an object doubles?

Back

If the velocity of an object doubles, its Kinetic Energy increases by a factor of four, since KE = 1/2 mv².
