Conservation of Energy-Unit 6 Review

Front

What is the Law of Conservation of Energy?

Back

Energy can be transformed from one form to another, but the total amount of energy in a closed system remains constant.

Front

What type of energy is associated with an object's position or condition?

Back

Potential Energy.

Front

What are the units for measuring work?

Back

Joules.

Front

What do you need to add to kinetic energy to find an object’s mechanical energy?

Back

Potential Energy.

Front

What type of energy is defined as the energy of motion?

Back

Kinetic Energy.

Front

What is Kinetic Energy?

Back

The energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

The energy stored in an object due to its position or configuration, such as gravitational potential energy.

Front

What is the work-energy theorem?

Back

The work done on an object is equal to the change in its kinetic energy.

Front

What is the formula for calculating work?

Back

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

Front

What is mechanical energy?

Back

The sum of kinetic and potential energy in a system.
