Warm-up
Find the six words related to forces and motion in the wordsearch below.[6]
Main test
/ Marks / Level1 / A car towing a caravan is travelling along a road.
(i) Draw an arrow on the diagram to show the direction of the force of the car pulling on the caravan. Label the arrow A.
(ii) Draw an arrow on the diagram to show what force the caravan exerts on the car. Label this arrow B. / [2] /
End-of-term test / Name
Form/Class
2 / Tick boxes to show two other forces that act on the car.
the weight of the caravan
the weight of the car
the mass of the car
the speed of the car
the thrust of the engine inside the car / [2] /
3 / There are two more forces that act on both the car and the caravan. The air causes one force as the car and caravan move. Another force changes depending on how rough the road is.
Name these two forces. / [2] /
4 / The graph shows the journey taken by the car and caravan.
(i) During the journey, the car stops in a traffic jam. Put the letter A on the graph to show where the car stops.
(ii) Use the graph to describe how long the car stops in the traffic jam. / [2] /
5 / The drawing below shows a camel.
Write down two ways in which the feet of a camel help it walk in soft sand. / [2] /
6 / The diagram shows a skydiver before he opens his parachute. The arrows show the direction of the forces acting on him.
Use the words below to complete the sentences. You may use the words more than once or not at all.
increase / stay the same / gravity
air resistance / decrease / friction
(i)Force A is caused by ______.
(ii)Force B is caused by ______.
(iii) When force B is bigger than force A, the speed of the skydiver downwards will ______.
(iv) When the parachute opens, force B will ______and force A will ______. / [5] /
7 / The diagram shows an ice cream van.
The van has a fault and leaks one drop of oil every second. The dots below show the drops left on the road as the van travels from A to D.
Describe the motion of the van as it moves:
(i) from A to B
(ii) from B to C
(iii) from C to D. / [3] /

Form/Class
8 / The ice cream van then travelled for 40 seconds at the constant speed of 11 m/s. Calculate the distance the van travelled. Show your working and give the unit. / [3] /
9 / Some military aeroplanes can travel at supersonic speeds.
The graph shows part of a journey completed by a jet plane.
Use the graph to work out:
(i) how far the plane travelled
(ii) how long it took the plane to travel a distance of 12 kilometres. / [2] /
10 / Calculate the speed of the plane. Show all of your workings and include the correct units. / [3] /
11 / A woman stands on a platform, A, before she does a bungee jump over a lake. She wears a harness attached to an elasticated rope. The rope reaches to point B when it is not being stretched.
A
B
C
D
Lake
The woman falls past point B and the rope starts stretching. She falls past point C to point D, which is the lowest point. She bounces back upwards again and comes to a rest at point C.
The graph shows how the woman’s speed changes as she falls from point A to D and then bounces back to C. The starting point A has been labelled on the graph. Label the points A, B, C and D on the graph to show how the jumper fell. / [3] /
12 / (i) At which point – A, B, C or D – is the woman when the tension force in the rope is greater than the force of her weight?
(ii) At which point – A, B, C or D –is the woman when the tension force in the rope is equal to the force of her weight? / [2] /
Six-mark question
When answering this question you need to:- use good English, paying attention to spelling and punctuation
- organise your information clearly with an introduction, an explanation and a conclusion
(you can use a table for the explanation if you prefer) - ensure that you use the correct scientific terms.
Answer the following question:
In 1971, during the Apollo 15 moonwalk, Commander David Scott performed a live experiment. He held out a hammer and a feather and dropped them at the same time.Describe and explain how the hammer and feather landed.[6]
