Front

What is the formula for calculating weight?

Back

Weight = mass × gravity (W = mg)

Front

What is the unit of measurement for force?

Newton (N)

Front

What is static friction?

Back

The friction that exists between a stationary object and the surface it's on.

Front

What is kinetic friction?

Back

The friction that occurs between moving surfaces.

Front

What is the difference between mass and weight?

Back

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