06c - Calculating Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

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

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv²

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state, commonly gravitational potential energy, calculated using PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the formula for calculating Gravitational Potential Energy?

Back

PE = mgh

Front

What factors affect Gravitational Potential Energy?

Back

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

If a soccer ball has a mass of 0.8 kg and is kicked with a velocity of 10 m/s, what is its Kinetic Energy?

Back

40 J

Front

A clock at the top of a 45m high tower weighs 20 kg. Calculate its Potential Energy. (g = 9.8 m/s²)

Back

8820 J

Front

What is the Kinetic Energy of a ping pong ball with a mass of 2.45 g moving at 4.0 m/s?

Back

19.6 J

Front

At which point in a pendulum's swing is Kinetic Energy highest?

Back

At the lowest point of the swing.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases.
