Q.1
How can the acceleration of an object be measured on a velocity time graph?
0%
By calculating the area under the graph
0%
By measuring the gradient
0%
By calculating the area above the graph
0%
You cannot work out the acceleration of an object from a velocity time graph
Q.2
What can affect the speed of a car?
0%
Air resistance
0%
Power of the engine
0%
Mass of the car
0%
All of the above
Q.3
When a resultant force acts upon an object, what determines the size of the acceleration of that object?
0%
Size of resultant force
0%
Mass of the object
0%
Size of resultant force and mass of the object
0%
Neither size of resultant force nor mass of the object
Q.4
If the resultant force acting on an object is zero, what happens to the object?
0%
It does not move
0%
It continues to move at a constant speed
0%
It does not accelerate
0%
All of the above
Q.5
In a vacuum, all bodies accelerate at what?
0%
The same rate
0%
A rate determined by their mass
0%
No two bodies accelerate at the same rate
0%
Either two times the strength of the field present or four times the strength of the field present
Q.6
As the speed of a car increases, what happens to the strength of the air resistance?
0%
Decreases
0%
Increases
0%
Stays the same
0%
There is no air resistance
Q.7
How can distance traveled be calculated by using a velocity time graph?
0%
It is the area under the graph
0%
It can be calculated from the gradient of the graph
0%
It cannot be calculated using a velocity time graph
0%
It is the area above the graph
Q.8
Which of the following surfaces will have the greatest frictional force?
0%
Smooth surface
0%
Rough surface
0%
Both smooth and rough have the same frictional force
0%
It is impossible to tell
Q.9
The equation that links mass, force and acceleration is ...
0%
Force = acceleration / mass
0%
Mass = force x acceleration
0%
Force = mass x acceleration
0%
Acceleration = mass x force

When the acceleration is 0
0%
When the acceleration is 1
0%
When the acceleration is less than 0
0%
When the acceleration is more than 1
