1.
The gradient of a speed-time graph is
distance
speed
acceleration
force
2.
A line rises from 6.0 m/s to 18 m/s in 4.0 s. The acceleration is
3.0 m/s2
4.5 m/s2
12 m/s2
0.33 m/s2
3.
A line falls from 20 m/s to 0 in 8.0 s. The acceleration is
+2.5 m/s2
−2.5 m/s2
−160 m/s2
+0.4 m/s2
4.
The distance travelled while the speed changes steadily from 4.0 to 12 m/s in 5.0 s is
20 m
60 m
8.0 m
40 m
5.
(Supplement) A speed-time graph becomes horizontal at the end of a curve. This shows
the object has stopped
the speed is zero
acceleration has become zero
distance is zero
6.
For which graph shape is the acceleration zero?
horizontal line
sloping straight line
steep curve
vertical line
