Object is speeding up

Object is slowing down

Direction is reversed

What is a reference point?

A source of energy for motion.

A stationary object used for measuring motion.

Any random object in motion.

An object that moves constantly.

How can distance be measured?

Estimated by guessing the length.

By counting the steps taken.

Only in straight lines.

Using units like meters, kilometers, or miles

S8P3.a

1

When is an object considered in motion?

When it changes position relative to a reference point.

Only if observed by someone.

If it rotates in place.

When it moves quickly only.
