Forces and Distance Time Graphs

What could an object be doing if the forces are unbalanced?

• steady speed

• accelerating

• stationary

What force pushes a rocket forwards

• thrust

• upthrust

• friction

• air resistance

What is the motion A to B?

• accelerating

• stationary

• steady speed

• decelerating

What is the motion between D to E

• steady speed

• accelerating

• decelerating

• stationary

How do you calculate speed?

• distance / time

• time / distance

• distance x time

• air resistance

• thrust

what does accelerating look like on a distance time graph?

• A curve up

• A straight diagonal line

• A curve down

• A flat horizontal line

What is the unit of force?

• N

• Kg

• m/s

• s

What is the motion from E to F?

• accelerating

• decelerating

• stationary

• returning to start
