APP1 Final Review

Front

What is the energy of motion called?

Back

Kinetic energy.

Front

What happens when the direction of an applied force is opposite to the direction an object is moving?

Back

Negative work is done.

Front

True or False: The more mass an object has, the faster it will fall.

Back

False.

Front

In a system of attached masses m1 & m2, which mass has a higher acceleration?

Back

Both will have the same acceleration because they're attached by a string.

Front

In uniform circular motion, what remains constant while the direction changes?

Back

The magnitude of speed remains constant, but the direction is continually changing.

Front

What is the definition of kinetic energy?

Back

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

Front

What is the formula for calculating work done?

Back

Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is uniform circular motion?

Back

Motion of an object traveling at a constant speed in a circular path.
