Front

What is friction?

Back

The resistance that one surface or object encounters when moving over another.

Front

Why do scientists conduct multiple trials in an experiment?

Back

To increase the reliability of results and ensure accuracy.

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 testable prediction about the outcome of an experiment.

Front

What is an experiment?

Back

A scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

Front

What is the purpose of a control in an experiment?

Back

To provide a standard for comparison and ensure that the results are due to the variable being tested.

Front

What is the effect of surface texture on friction?

Back

Rough surfaces create more friction than smooth surfaces.
