5.6D & 3.6B Force and Experimental Design

Front

What is friction?

Back

A rubbing force that opposes motion between two surfaces that are in contact. Rough surfaces have more friction and smooth surfaces have less friction.

Front

What is resistance in terms of forces?

Back

Frictional forces that act against a moving object.

Front

What is data in scientific terms?

Back

Evidence; information gathered from observations.

Front

What is the unit of force?

Back

Newton (N).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
