Y7 Forces
Y7 P1.1 Forces
In this question you will be assessed on using good English, organising information clearly and using specialist terms where appropriate.
An organiser of a bungee jumping competition changes the length of the bungee rope so different people can use the rope safely. Use your idea of forces to describe how the size of a person affects the rope when they jump.
Extra information: The rope is 15 m long and it extends by 3 m when an adult jumps. An adult weighs twice as much as a child. (6)
Q1. Zoë wants to investigate the way rock is worn away by running water.She uses a long piece of ice rather than a piece of rock.She places the ice in a sink and lets a thin stream of cold water run slowly over it.
(a) The thin stream of water starts to change the shape of the piece of ice.What shape would form in the top of the piece of ice?
......................................................................................................................1 mark
(b) Zoë’s experiment was not a good way of showing how rocks are worn away by water. The ice was worn down a little, but mostly it got smaller for a different reason.Why did the piece of ice get smaller?
......................................................................................................................1 mark
Zoë measures the height of the piece of ice at different times. She plots a bar chart of her results.
(c) Draw in the bar for the height of the ice after 3 minutes.1 mark
Maximum 3 marks
Q2. John and Sarah investigated how pupils in their class were the same and different.First they measured the length of each pupil’s little finger.
(a) Why should each pupil keep their little finger straight while it was being measured?
.............................................................................................................1 mark
(c) John and Sarah then counted the number of pupils who can andcannot roll their tongues.What method did they use to collect their data?Tick the correct box.
Observe pupil’s tongues. Look at books.
Identify factors to keep the same.
Measure pupil’s tongues.
1 mark
(d) They recorded their results in a table.
results for investigation 2
can roll tongue cannot roll tongue
10 4
Draw a bar on the chart below to show how many pupils can roll their tongues.
1 mark
(e) Look at their bar charts for investigations 1 and 2.How can you tell that they used different numbers of pupils in each investigation?

Q3. Paula made a pendulum from a ball attached to a piece of string.
She counted the number of swings the ball made in 10 seconds.She repeated the experiment with different lengths of string.
The table below shows Paula’s results.
length of string (cm) number of swings in 10 seconds
10 16
20 11
30 9
40 8
50 7
(a) What happens to the number of swings when the string gets longer?
......................................................................................................................1 mark
(b) Paula drew a graph of her results.
(i) Write the labels on both axes of the graph below.Use the table to help you.
2 marks
(ii) Paula made a pendulum from a piece of string that was 15 cm long.How many times would this pendulum swing in 10 seconds?Use the graph to help you.
.......................1 mark
(iii) Paula made a pendulum from a piece of string that was 60 cm long.Estimate the number of swings the pendulum makes in 10 seconds.Use the graph.Tick the best answer.
18 12 6 4 1 mark
(c) After some time the pendulum stops moving.What force makes the pendulum stop moving?
.........................................................1 mark
maximum 6 marks
c. Gravity
Q1. (a) The diagram shows Alan sitting on a ride at a theme park.
(i) Which arrow shows Alan’s weight?
Give the correct letter. ..................................1 mark
(ii) Alan begins to move forwards. Which arrow shows the force which makes Alan move faster?
Give the correct letter. ..................................1 mark
(b) During the ride, Alan is upside down.
Draw an arrow on the diagram to show the direction of Alan’s weight while he is upside down.
1 markMaximum 3 marks
Q2. The diagram below shows the path of a meteor as it gets closer to the Earth.The meteor is shown in three positions: A, B and C.
not to scale
(a) The path of the meteor is affected by the Earth’s gravity.The arrow shows the direction of the force due to gravity acting on the meteor at B.
(i) On the diagram draw an arrow to show the direction of the force of gravity on the meteor at A.Use a ruler.
1 mark
(ii) On the diagram draw an arrow to show the direction of the force of gravity on the meteor at C.Use a ruler.
1 mark
(iii) How does the force of gravity on the meteor change as it travels from A to C?
......................................................1 mark
(b) What happens to the speed of the meteor as it travels from A to B?
......................................................1 mark
(c) When the meteor enters the Earth’s atmosphere, three forces act on the meteor. Gravity and upthrust are two of these forces.
Give the name of the other force.
......................................................1 mark
