The wheel of a moving car is driven by the engine. The car is accelerating in the direction shown.

1.   ?    A
2.   ?    B
3.   ?    C
4.   ?    D

The diagrams show the same object on a smooth table. Four different pairs of forces act on the object.

1.   ?    A
2.   ?    B
3.   ?    C
4.   ?    D

A force is applied to an object on a frictionless surface. It produces an acceleration of 3 m/s².

What are possible values for the applied force and for the mass of the object?

1.   ?    force: 2 N; mass: 5 kg
2.   ?    force: 2 N; mass: 6 g
3.   ?    force: 5 N; mass: 2 kg
4.   ?    force: 6 N; mass: 2 kg

A horizontal force of 8 N is applied to a block of mass 2 kg, resting on a frictionless table.

What is the acceleration of the block?

1.   ?    0.25 m/s²
2.   ?    4.0 m/s²
3.   ?    6.0 m/s²
4.   ?    16 m/s²

A heavy lorry has high inertia.

How difficult is it to start it moving and to stop it moving?

1.   ?    to start: difficult; to stop: difficult
2.   ?    to start: difficult; to stop: easy
3.   ?    to start: easy; to stop: difficult
4.   ?    to start: easy; to stop: easy

The diagrams show some effects which are due to same physical property.

1.   ?    Friction
2.   ?    Heat
3.   ?    Mass
4.   ?    Weight

A body with a mass of 10 kg is placed on a frictionless surface. It is pulled by a spring balance and the acceleration
is 5 m/s².
What should the reading on the spring balance be?

1.   ?    10 N
2.   ?    50 N
3.   ?    500 N
4.   ?    15 N

Where is friction usually employed in a car?

1.   ?    Its tyres
2.   ?    Its battery
3.   ?    Its radiator
4.   ?    Its horn

Which expression can be used to calculate force?

1.   ?    mass = force / acceleration
2.   ?    mass = force x acceleration
3.   ?    power = force x time
4.   ?    work = force / distance

The object in the diagram is acted upon by the two forces shown.

1.   ?    The object moves to the left with constant speed.
2.   ?    The object moves to the left with constant acceleration.
3.   ?    The object moves to the right with constant speed.
4.   ?    The object moves to the right with constant acceleration
