P4-Physical Science Semester Final

Front

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

Back

Kinetic energy quadruples.

Front

Does a stationary object have kinetic energy?

Back

No, a stationary object has no kinetic energy.

Front

What does Newton's Third Law state about forces?

Back

For every action, there is an equal and opposite reaction.

Front

If the mass of an object increases, what happens to the force needed to achieve the same acceleration?

Back

More force is needed.

Front

What type of energy transformation occurs when a rocket lifts off?

Back

Chemical potential energy transforms into kinetic and thermal energy.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How is kinetic energy calculated?

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

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

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma, where F is force, m is mass, and a is acceleration.
