2.1.4 Gradient of a Displacement-Time Graph – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
The gradient of a displacement-time graph is
acceleration
distance
jerk
velocity
2.
At the moment two lines cross on an s-t graph, the two objects
have equal velocity
are at the same position
have equal acceleration
are at rest
3.
A tangent to an s-t curve rises 9.0 m over 3.0 s. The instantaneous velocity is
3.0 m s-1
0.33 m s-1
27 m s-1
12 m s-1
4.
An s-t curve that becomes less steep with time shows
constant velocity
increasing velocity
negative acceleration only
decreasing velocity
5.
The best way to find instantaneous velocity from a curved s-t graph is to
divide s by t at the point
draw a tangent and measure its gradient
use the gradient of a chord between far-apart points
find the area under the curve
6.
A horizontal section of an s-t graph shows
uniform acceleration
constant velocity
rest
free fall
