Potential and Kinetic Energy

Front

What is the equation for calculating an object's gravitational potential energy?

Back

PE = mgh, where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height.

Front

Where do animals have the most potential energy when running around a loop?

Back

At the top of the loop.

Front

What type of energy is stored due to an object's height and the acceleration of gravity?

Back

Gravitational Potential Energy.

Front

How do you calculate the kinetic energy of an object?

Back

KE = 0.5 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The kinetic energy increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy stored in an object as a result of its vertical position or height.

Front

If an object has a mass of 5 kg and is at a height of 10 m, what is its gravitational potential energy?

Back

PE = mgh = 5 kg * 9.8 m/s² * 10 m = 490 Joules.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object.

Front

If a car is moving at 20 m/s, what happens to its kinetic energy if its speed doubles?

Back

The kinetic energy increases by a factor of four.
