Mass & Force

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in grams or kilograms.

Front

What is force?

Back

Force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What does friction produce?

Back

Friction produces heat.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two variables.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured in an experiment, often affected by changes in the independent variable.

Front

What is an independent variable?

Back

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

Front

What is the effect of increasing mass on the force needed to move an object?

Back

Increasing the mass of an object requires more force to move it.

Front

What is the effect of surface type on friction?

Back

Different surfaces produce different amounts of friction, affecting how easily objects can move over them.
