What is a Controlled Variable?

Back

A variable in an experiment that remains constant and does not change.

Front

What is an Independent Variable?

Back

The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a Dependent Variable?

Back

The variable that is measured and affected in an experiment.

Front

What is Work in physics?

Back

Work is done when a force causes an object to move. If there is no movement, no work is done.

Front

What is Conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is Convection?

Back

The transfer of heat by the movement of fluids (liquids or gases).

Front

What is Radiation?

Back

The transfer of energy through space by electromagnetic waves.

Front

What does Newton's 1st Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does Newton's 2nd Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What does Newton's 3rd Law state?

Back

For every action, there is an equal and opposite reaction.
