Physics Review #1

Front

What type of energy does a boulder have while on top of a hill?

Back

Potential energy is the energy stored in an object due to its position or height.

Front

What happens to the potential and kinetic energy of a pendulum as it swings from its highest to lowest position?

Back

The potential energy decreases while the kinetic energy increases.

Front

What is the definition of net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What is the energy of motion called?

Back

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

Front

If an object is pushed to the right, how will it move?

Back

It will move to the right.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.

Front

What is the relationship between mass and kinetic energy?

Back

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

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.
