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