75 minutes
1.25 minutes
48 minutes
@A person walks 50m in 30 seconds and then rests for 30s. They walk back, this time taking 40s. What is the average speed?
1.0 m/s
0.71 m/s
1.67 m/s
@Which one of the following is TRUE?
Speed is a scalar and velocity is a vector
Speed is a vector and velocity is a vector
Both speed and velocity are vectors
@The slope of a distance-time graph is a measure of:
Speed
Acceleration
Displacement
@A curved distance-time graph means that:
Speed is changing
Speed is increasing
Speed is constant
The diagram shows four velocity-time graphs. Which is the correct shape for an object moving at a constant velocity?
#mot2
Graph w
Graph z
Graph x
@Which of these velocity-time graphs is for an object that is accelerating?
#mot2
Graph x
Graph y
Graph w
@A bicycle travels in a large circle. What can be said about its speed and velocity?
The speed is constant but the velocity is constantly changing
Both the speed and velocity can remain constant
The speed might change, but the velocity will always be constant
@Which of these velocity time graphs was produced by an object that was slowing down?
#mot2
Graph y
Graph x
Graph z
@The graph shows a distance-time graph as a person walked on a journey. What was happening at region (x) ?
#mot1
They were not moving
They were walking slowly, away from the starting point
They turned around and started to come back
@The distance-time graph is shown for an object. At which two regions is the object not moving?
#mot1
z and x
w and z
y and z
@A distance-time graph is shown for an object. What is happening at region (y)?
#mot1
The object moves back towards its starting point
The object becomes stationary for a while
The object moves even more quickly
@A distance-time graph is shown for an object. At which point is the object moving back towards the starting point?
#mot1
Region y
Region x
Region w
@A distance-time graph is shown for an object. Which statement is correct?
#mot1
The object was stationary twice
The object was never stationary
The object was only stationary once
@An object dropped into a large deep container of syrup:
reaches terminal velocity very quickly
never reaches terminal velocity
may just reach terminal velocity
