What is the definition of kinetic energy?

Back

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

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often associated with gravitational energy when an object is elevated.

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if velocity remains constant.

How does speed affect kinetic energy?

Back

Kinetic energy is proportional to the square of the speed; as speed increases, kinetic energy increases exponentially.

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy increases with the square of the velocity, meaning if the velocity doubles, the kinetic energy increases by a factor of four.

What factors affect potential energy?

Back

Potential energy is affected by the mass of the object and its height above a reference point, typically calculated using PE = mgh, where g is the acceleration due to gravity.

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

How can you increase the kinetic energy of an object?

Back

You can increase the kinetic energy of an object by increasing its mass, increasing its speed, or both.
