with constant speed? - ANS>a slanted line
What is the shape of a distance-time graph when the object is moving
with changing speed? - ANS>a curved line
What is the distance traveled for motion with constant acceleration in a
speed-time graph? - ANS>the area under the graph
If a body accelerates its speed-time graph will have a... - ANS>positive
gradient
If a body decelerates its speed-time graph will have a... - ANS>negative
gradient
What is the difference between speed and velocity? - ANS>Velocity is a
vector while speed is scalar. Velocity has a direction.
a = - ANS>∆v÷t
, Speed (on a distance-time graph) = - ANS>the gradient
