Use your notes to help you answer each question.

Take your time.

PAY CAREFUL attention to the TYPE of graph you are looking at!

1

What does a negative acceleration indicate?

No change in motion

Object is speeding up

Object is slowing down

Direction is reversed

S8P3.a

1

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.

S8P3.a

1

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.

Mmuae Afoforo a Wobɛpaw:

a car remains parked in a car park

a motorbike travels away from home at a steady speed

a runner runs at a steady pace to the end of a trick turns around and runs at the same speed back

S8P3.a

1

What does a straight horizontal line on a distance-time graph represent?

No motion over time.

Object moving backwards.

Constant speed forward.

Speed is increasing.

S8P3.a

How many times does this object stop moving?

thrice

not at all

twice

once

S8P3.a

If a distance-time graph has a positive slope, what does it indicate?

Object is stationary.

Object is moving away from the starting point.

Object is moving backward.

Object is moving in circles.

S8P3.a

1

What does a steeper slope on a distance-time graph show?

Slower than before.

No movement occurs.

Faster speed of the object.

Constant speed only.
