Unit 2 Post Test Review

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

How does mass affect Kinetic Energy?

Back

As mass increases, Kinetic Energy increases, provided the speed remains constant.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

If two objects are moving at the same speed, how does their mass affect their Kinetic Energy?

Back

The object with greater mass will have more Kinetic Energy.

Front

What happens to Kinetic Energy if the speed of an object doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the speed.

Front

What is the relationship between speed and Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed; as speed increases, Kinetic Energy increases rapidly.

Front

Can an object have Kinetic Energy if it is at rest?

Back

No, an object at rest has zero Kinetic Energy because it is not in motion.

Front

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 does Kinetic Energy relate to everyday activities?

Back

Kinetic Energy is involved in activities like walking, running, and driving, where moving objects possess energy due to their motion.

Front

What is an example of Kinetic Energy in sports?

Back

A soccer ball being kicked has Kinetic Energy due to its motion towards the goal.
