Final Exam Revision

The following distance-time graph shows a car's journey. [a] How far did the car travel in the first 3 seconds?

• 20

• 40

• 60

The following distance-time graph shows a car's journey.

[b] For how long was the car stationary?

• 2

• 4

• 6

The following distance-time graph shows a car's journey.

[c] What was the car's greatest speed?

• 20

• 50

• 60

is equal to its rise over its run

• The slope of a line

• Acceleration

• Velocity

is a measure of the rate of change of velocity of an object with respect to time. It is a vector quantity, which means it has both magnitude and direction.

• The slope of a line

• Acceleration

• Velocity

Δv = change in velocity

• (m/s²)

• (m/s)

• (s)

a = acceleration

• (m/s²)

• (m/s)

• (s)

A car increasing its speed from 0 to 60 km/h in 10 seconds has

• positive acceleration

• negative acceleration.(Deceleration)

• Uniform Acceleration

When an object’s acceleration is constant, its instantaneous and average accelerations are the same.

• True

• False

velocity and acceleration have

• direction associated with them

• both are vector

• rates of change

• all of the above
