Front

What is the unit called that measures force?

Back

Newton

Front

What type of friction is not moving?

Back

static

Front

What is Friction?

Back

When 2 objects slide against each other

Front

Why do we need friction?

Back

It helps make objects go slower or stop.

Front

The law of inertia (Newton's first law) applies _____?

Back

to both moving and nonmoving objects.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the difference between mass and weight?

Back

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

Front

What is kinetic friction?

Back

Friction that occurs when two objects are sliding against each other.

Front

What is the effect of increasing mass on gravitational force?

Back

Increasing mass increases the gravitational force.
