Kinetic energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What happens to kinetic energy when an object's speed increases?

Back

Kinetic energy increases when an object's speed increases.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass. A heavier object moving at the same speed has more kinetic energy than a lighter object.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is speed.

Front

If two objects have the same mass, how does speed affect their kinetic energy?

Back

The object with the higher speed will have more kinetic energy.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

Can an object have kinetic energy if it is not moving?

Back

No, an object must be in motion to have kinetic energy.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a thrown ball, or a flowing river all have kinetic energy.

Front

How does kinetic energy relate to potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position. They can convert into each other.

Front

What happens to the kinetic energy of a ball thrown upward as it rises?

Back

As the ball rises, its kinetic energy decreases while its potential energy increases.
