Kinematics Junior 2

If the speed of an object does NOT change, the object is traveling at a(n) _____________.

• increasing speed

• decreasing speed

• constant speed

• average speed

If a bicyclist travels 30 km in 2 hours, her average speed is ___________.

• 60 km/h

• 15 m/s

• 0.067 km/h

• 15 km/h

How fast is the car traveling at 30 seconds?

• 5 m/s

• 10 m/s

• 20 m/s

• 30 m/s

Acceleration only takes place when things speed up. 

• True

• False

When are you undergoing an acceleration in a car? 

• speed up

• slow down

• make turns

• All of the above 

What is happening in this graph from point B to C?

• The object is going down a hill.

• The object is returning to its starting location.

• The object is slowing down.

• The object is staying still.

Which part of the line shows the constant POSITION?

• A to B

• B to C

• C to D

• D to E

What is the formula to calculate speed?

• Speed = Distance x Time

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Time x Distance

All of the following are units of speed except:

• km / h

• km

• kilometer per hour

• kilometer / hour

How would you calculate the average speed for a car that went a distance of 125 kilometers in 2 hours time?

• 125 × 2

• 125 ÷ 2

• 2 ÷ 125

• 2 + 125
