9.2 Velocity - time graphs

Question 1

What is the y axis, and x axis in a velocity-time graph?

Answer 1

» Velocity on y axis
» Time on x axis

Question 2

What does a horizontal line at v = 0 represent?

Answer 2

» Velocity is zero and the object is stationary

Question 3

What does a horizontal line represent?

Answer 3

» The velocity is unchanging and the object is moving with constant velocity

Question 4

What does a constant gradient in a velocity-time graph represent?

Answer 4

» The velocity is increasing at a constant rate
» Object is moving with constant acceleration

Question 5

What is acceleration?

Answer 5

» The rate of change of velocity

Question 6

What does the gradient in a velocity time graph represent?

Answer 6

» Acceleration

Question 7

What does a straight line in a velocity-time graph represent?

Answer 7

» The acceleration is constant

Question 8

What does the area under a velocity-time graph represent?

Answer 8

» The area as:
» Velocity x time = displacement
» Displacement/time = velocity
