The gradient of a velocity-time graph represents __________.
speed
distance
displacement
The area under a velocity-time graph represents __________.
total distance

total velocity
Describe the motion in section D.
(a)
Calculate the acceleration in section A
(a)
State the size of the acceleration in section B.
(a)
Part D of the graph is from 55s to 95s. During Part D, the velocity values are all negative. What does negative velocity mean?
The object is slowing down.
The object is moving in the opposite direction now.
During section A of the graph (between 0s and 25s), the object is accelerating.
Change in velocity in this time = 3 - 0 = 3m/s
Time taken = 25 - 0 = 25s
What is its acceleration?
Acceleration = Change in velocity x time = 3 x 25 = 75m/s2
Acceleration = Change in velocity / time = 3/25 = 0.12m/s2
What is the unit for displacement?
m
s
m/s
m/s/s
What is the unit for velocity?
m
s
m/s
m/s/s
The slope of a velocity - time graph represents?
Velocity
Displacement
Acceleration
Time
what is the formula for acceleration?
a=ΔtΔv
a=td
