1. The diagram shows a helicopter in the air.
The arrows show the directions of the four
forces which can act on it.

equal for the helicopter to stay at the same height.
Which two forces?

in its flight.
(b)
Draw
an arrow on this diagram to show which direction the helicopter will
move. [1]

next diagram shows the direction of one force, C, acting on the
helicopter.

acting on the helicopter when it is on the ground.
Draw an arrow on the diagram to show the direction of this other
force. [1]

fact to match its observation.

fuel.

(e) State one disadvantage
to the environment of cutting down trees to get wood for fuel?
....................................................................................................................................................................................................................................................................[1]
4. Simran has been measuring the time
taken for different objects to slide down a ramp. The picture shows the ramp
with one of the objects, a pencil case, on it.
(a) On the picture, draw
an arrow to show the direction of the force of friction on the pencil case. [1]
(b)
(b) When timing the
different objects, the test should be made fair.
One factor to keep constant is the
distance that the object slides.
State two other factors
which need to be kept the same for each test.
1..................................................................................................................................
2..............................................................................................................................[2]
Simran repeats the test with the
pencil case and records the results in this table.
She thinks there may be something
wrong with her second time.
(c) Why might she think
this?
....................................................................................................................................
................................................................................................................................[1]
(d) How could she check
if the second time was wrong?
....................................................................................................................................
...............................................................................................................................[1]
5. Complete the boxes beside each
picture to record the reading on each piece of
equipment.
(a)
Measuring cylinder in cm3.
[1]
(b)
Voltmeter in volts.
6. Complete the table to show the
useful energy transfer that happens in each case.
The first one has been done for you.
[3]
7. Liz and Rena investigate how high a
ball bounces. They use a metre ruler and a tennis ball.
Liz drops the ball
from different heights.
Rena watches and
records the height of the first bounce.
They measure the
height from the bottom of the ball.
(a) Write down one reason
why Rena will find it difficult to record the height of the bounce accurately.
....................................................................................................................................
................................................................................................................................[1]
Liz and Rena repeat each test three
times and work out the average for each.
They measure in centimetres (cm).
They record their results in the table
below.
They have plotted three of their
results on a graph.
(b) Complete the graph
by:
• plotting the last two points
• drawing a best fit straight line.
[2]
(c) One advantage of
plotting a graph is that the trend can be seen more clearly than in the
table.
Write down one other advantage of displaying results in a graph.
....................................................................................................................................
................................................................................................................................[1]
(d) Another group in the
class does the test.
They plotted their results on a
similar graph.
Their points were all far from their
line.
What does this suggest about their
results?
...................................................................................................................................
................................................................................................................................[1]
8. Andy and James are pulling on a
rope.
The size and direction of their pulling forces are shown.
(a) The rope does not move
toward Andy or James.
Explain why the rope does not move.
....................................................................................................................................
....................................................................................................................................
....................................................................................................................................
................................................................................................................................[2]
(b) Andy keeps pulling
with the same force of 100 N.
The rope now starts to move towards
him.
What must have happened to the pulling
force from James?
....................................................................................................................................
...............................................................................................................................[1]
9. The diagram shows four large
objects, A to D, at different places on the Earth’s surface.
(a) Draw arrows from the
objects to show the force of gravity on them.
The first one has been done for you. [2]
(b) The Moon has a
smaller force of gravity than the Earth.
Use this information to complete the sentences.
Use the words from the list below.
greater the same less
The mass of object A will be
..................................... when placed on the Moon.
The weight of object A will be
...................................... when placed on the Moon.[2]
