For a vehicle moving in a straight line, which one of the following physical quantities could be determined by finding the gradient of its velocity-time graph?
average displacement
acceleration
instantaneous displacement
average velocity
The velocity-time graph represents the movement of a train on a straight horizontal track. What is the average speed in m.s-1, of the object for the interval 0 s to 15 s?
Hint: First determine the total displacement.
7,67
10
80
115
Which of the following acceleration time graphs represents a free falling object?
The velocity-time graph represents the motion of a motor car which begins to move in an easterly direction.
The car moves in a westerly direction between ....
C and E
D and F
D and E
C and D
A steel ball rolls from rest down a ramp with a constant acceleration. Which one of the following displacement-time graphs bests represents the relationship between the displacement and the time corectly? (Friction is negligible and can therefore be ignored)
NOTE: "s" is the old symbol used to represent displacement
The motion of two objects, A and B, is shown in the displacement-time graph.
NOTE: "s" is the old symbol used to represent displacement
The graph shows that:
Both A and B began moving from rest at the same instant
