# Multiple choice questions

Multiple choice questions are perhaps the easiest to complete - you simply put a cross in a box - however, the questions often have two answers that could, at first glance, be correct. Don't make the mistake of reading the first answer and thinking this is correct without checking all the others.

If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes you will get zero marks. These multiple choice questions will not start with command words like 'describe' or 'explain'. They will be written in the form of a question like 'What…?' or 'Why…?'.

There will be more multiple choice questions on the Foundation paper.

## Sample question 1 - Foundation

Question

Force is a vector quantity.

Which is a correct statement about a vector quantity? [1 mark]

Tick one box.

A Has direction only Has direction and magnitude Has magnitude only Has neither magnitude nor direction
 A Has direction only B Has direction and magnitude ✔ C Has magnitude only D Has neither magnitude nor direction

A vector quantity has direction and magnitude. A scalar quantity has magnitude only.

## Sample question 2 - Foundation

Question

The figure shows the forces acting on a car moving at a constant speed.

Which force would have to increase to make the car accelerate? [1 mark]

Tick one box.

A ✔

In order to make the car accelerate, the resultant force must be forwards. Force C needs to increase.

## Sample question 3 - Higher

Question

What is the unit of momentum? [1 mark]

Tick one box.

A J/s kg m/s N m m/s2
A B J/s kg m/s ✔ N m m/s2

Momentum is the product of mass (measured in kg) and velocity (measured in m/s), therefore the unit of momentum is kg m/s.

## Sample question 4 - Higher

Question

The figure below shows the horizontal forces acting on a car.

Which one of the statements describes the motion of the car? [1 mark]

Tick one box.

 A It will be slowing down. B It will be stationary. C It will have a constant speed. D It will be speeding up.
 A It will be slowing down. B It will be stationary. C It will have a constant speed. ✔ D It will be speeding up.

If the forces on an object are balanced (ie there is no resultant force) it will remain stationary or continue travelling at a constant speed. The car cannot be stationary, as the drag forces (air resistance/friction) only occur when an object is moving. Since the forces shown are due to the force of the engine and air resistance then the car must be moving at a constant speed.
