Unit 4 Review

Front

What does the law of Conservation of Energy state?

Back

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

Front

How do you calculate Net Force when forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the result of balanced forces acting on an object?

Back

The object remains at rest or continues to move at a constant velocity (Net Force = 0 N).

Front

What type of wave has particles that vibrate parallel to the direction of wave travel?

Back

Longitudinal wave.

Front

What is the unit used to measure energy?

Back

Joules.

Front

What is the formula for calculating Net Force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is an example of energy transformation?

Back

A battery converting chemical energy into electrical energy.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

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 the definition of a transverse wave?

Back

A wave in which the medium's particles move perpendicular to the direction of the wave.
