Unit 1 & 2 Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

Front

At which point will the cars have the greatest amount of potential energy?

Back

The cars will have the greatest amount of potential energy at the highest point, which is point 1.

Front

What is a homogenous mixture?

Back

A homogenous mixture is a mixture that has a uniform composition throughout. The individual components are not distinguishable.

Front

What is a mechanical energy transformation?

Back

A mechanical energy transformation occurs when energy changes from one form to another, such as from potential energy to kinetic energy.

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the difference between an element and a compound?

Back

An element is a pure substance made of only one type of atom, while a compound is a substance formed when two or more different types of atoms bond together.
