Forces, friction and gravity basics

Front

What is the unit used to measure force?

Back

Newtons

Front

What direction does friction move when compared to an applied force?

Back

Friction moves in the opposite direction of the applied force.

Front

Sally experiences some forces while playing on a slide. Which force pulls her body down the slide and which force helps her come to a stop at the end of the slide?

Back

Gravity pulls her down the slide and friction helps her stop at the end.

Front

Cooper is riding his skateboard on a flat smooth surface. If friction could be completely eliminated, what would happen to Cooper and his skateboard once he started rolling?

Back

Cooper and his skateboard would keep going at the same speed and direction and would not stop unless acted on by another unbalanced force.

Front

What is defined as a push or pull?

Back

force

Front

Name at least two forces experienced by swimming fish?

Back

Gravity, Buoyancy or Buoyant Force, and fluid friction. (any 2 of these)

Front

Explain what, if any, movement will occur? Why?

Back

The object won't move because the forces pushing against each side are balanced. Balanced forces don't move.

Front

One of these (mass or weight) depends on the amount gravitational force, the other is always the same no matter what the gravitational force is. Which measurement is always the same?

Back

Mass

Front

Mass is the amount of _________ that makes up an object.

Back

matter

Front

What causes an object to begin moving?

Back

Applied Force or Unbalanced Force
