PS.6 States and Forms of Energy

Front

What does the law of conservation of energy state?

Back

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

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by mass and velocity.

Front

What is an example of electrical energy?

Back

Lightning during a thunderstorm is an example of electrical energy.

Front

What causes a pendulum to eventually slow and stop?

Back

A pendulum slows and stops due to friction.

Front

Which skier has greater potential energy if one is higher than the other?

Back

The skier who is higher has greater potential energy.

Front

Define kinetic energy.

Back

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

Front

Define potential energy.

Back

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

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is associated with the position of an object?

Back

Potential energy is associated with the position of an object.
