What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that in a closed system, the mass of the reactants must equal the mass of the products; matter cannot be created or destroyed.

Front

How does kinetic energy (KE) relate to mass?

Back

Kinetic energy increases as mass increases, assuming velocity remains constant.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What determines the potential energy of an object?

Back

Potential energy is determined by an object's mass and its height above the ground.

Front

Which has greater potential energy: a heavy object at a low height or a light object at a high height?

Back

The heavy object at a low height may have less potential energy than the light object at a high height, depending on the specific values of mass and height.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

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

Front

How can you increase the potential energy of an object?

Back

You can increase the potential energy of an object by increasing its height or mass.

Front

What is the relationship between height and potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What happens to the total energy in a closed system?

Back

The total energy in a closed system remains constant; energy can change forms but cannot be created or destroyed.
