1
Q
what does the height of an acceleration-time graph give?
A
the objects acceleration at that time
2
Q
how is deceleration shown on an acceleration-time graph?
A
with a negative value of acceleration
3
Q
what does a positive gradient mean on an acceleration-time graph?
A
rate of acceleration is increasing
4
Q
how do you find the change in velocity from an acceleration-time graph?
A
