7.3 Test Review

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and speed of an object.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of the particles in a substance.

Front

Kinetic Energy is the energy of __________.

Back

movement.

Front

Objects with MORE MASS have _____________.

Back

higher thermal energy.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is potential energy?

Back

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

Front

How does mass affect kinetic energy?

Back

The greater the mass of an object, the greater its kinetic energy when moving at the same speed.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is the relationship between temperature and kinetic energy?

Back

As the temperature of a substance increases, the average kinetic energy of its particles also increases.
