Review for Quarterly Assessment 3

Front

What is Elastic Energy?

Back

Elastic Energy is the potential energy stored in an object when it is compressed or stretched, such as in springs or rubber bands.

Front

What does Exothermic mean?

Back

Exothermic refers to a process or reaction that releases energy, usually in the form of heat.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What is Activation Energy?

Back

Activation Energy is the minimum energy required for a chemical reaction to occur.

Front

What is a Pulley?

Back

A Pulley is a simple machine that consists of a wheel on an axle or shaft designed to support movement and change the direction of force.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in a system, representing the energy associated with the motion and position of an object.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, such as gravitational potential energy.

Front

What is the difference between Exothermic and Endothermic reactions?

Back

Exothermic reactions release energy, while Endothermic reactions absorb energy.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is a Simple Machine?

Back

A Simple Machine is a device that changes the direction or magnitude of a force, making work easier.
