Physical Science Module Test Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity, calculated using the formula KE = 1/2 mv².

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 rusting?

Back

Rusting is a chemical reaction that occurs when iron reacts with oxygen and moisture, resulting in iron oxide, commonly known as rust.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another, involving the breaking and forming of bonds.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the significance of a color change in a chemical reaction?

Back

A color change can indicate that a chemical reaction has occurred, often signaling the formation of new substances.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in a substance.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves, which can be heard when they reach a person's or animal's ear.

Front

What is the formula for calculating kinetic energy?

Back

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