• True

• False

When an object is moving at a constant speed it is being acted upon by a net force.

• True

• False

When an object is accelerating it is being acted upon by a net force.

• True

• False

In order to determine the motion of an object a/an ________________ is needed.

• focal point

• optical point

• vantage point

• reference point

It describes how far an object has moved.

• range
