Answer:
Uniform acceleration means that the object is accelerating at a constant rate. Since there is still acceleration, velocity is not constant. In fact, the velocity is increasing. This means that the object is moving faster and faster at a constant rate.
This graph is a displacement-time graph so its gradient would represent the velocity of the object. The velocity increases hence the gradient should increase (which means that the graph must be steeper and steeper with increasing time).
Constant gradient of a displacement-time graph would mean that there is no acceleration since gradient of the graph does not change so velocity is constant.
Note that it is the<em> </em><em>rate</em><em> </em><em>of</em><em> </em><em>change</em> of velocity that is constant during uniform acceleration, not velocity.
Answer:
0.8m per second
Explanation:
we measure speed as distance over time
distance=8m
time=10s
therefore speed = 8/10
=0.8m per second
