Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is the energy that has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity, calculated using the formula KE = 1/2 mv².

Front

At which point is potential energy greatest in a vertical system?

Back

Potential energy is greatest at the highest point in a vertical system.

Front

At which point is kinetic energy greatest in a vertical system?

Back

Kinetic energy is greatest at the lowest point in a vertical system.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

If a car has a mass of 1120 kg and is traveling at 40 m/s, what is its kinetic energy?

Back

The kinetic energy of the car is 896,000 J.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of an object above a reference point and the mass of the object.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, demonstrating the conservation of energy in a closed system.

Front

If an object is lifted to a height, what happens to its potential energy?

Back

As an object is lifted to a height, its potential energy increases due to the increase in height.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object possesses due to its position in a gravitational field, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.
