8 worked examples below. Covers forces, energy, waves, electricity and nuclear physics.
Worked Physics questions Physics Year 7 Forces Easy 2 marks
1. The diagram shows forces on a box. The forces are 30 N left and 50 N right. Which way does the box move?
A Rightcorrect B LeftC It stays stillD UpwardsThe method
The box moves in the direction of the larger force.
Worked solution
The right force is larger, so the box moves to the right.
Mark scheme
1 mark for right.
Common mistake
Adding the forces instead of comparing them.
Exam tip
Compare opposing forces. The bigger one wins.
Physics Year 8 Energy transfers Easy 2 marks
2. A torch changes chemical energy in the battery mainly into which two stores?
A B C
A Light and heatcorrect B Sound and lightC Kinetic and soundD Elastic and heatThe method
Think about the useful and wasted output of a torch.
Worked solution
A torch gives out light energy, with some wasted as heat.
Mark scheme
1 mark for light and heat.
Common mistake
Saying sound, which a torch does not produce.
Exam tip
Useful light, with heat as the main waste.
Physics Year 9 Waves Medium 2 marks
3. The diagram shows a wave. Distance A from the middle to the top is called what?
A Amplitudecorrect B WavelengthC FrequencyD PeriodThe method
The height of a wave from the centre has a special name.
Worked solution
Distance A from the rest line to the peak is the amplitude.
Mark scheme
1 mark for amplitude.
Common mistake
Confusing amplitude with wavelength.
Exam tip
Amplitude is height from the middle. Wavelength is along the wave.
Physics Year 10 Forces and motion Hard 2 marks
4. A force of 20 N acts on a mass of 4 kg. Work out the acceleration in metres per second squared.
Answer: 5
The method
Use the equation force equals mass times acceleration, rearranged for acceleration.
Worked solution
a = F / m = 20 / 4 = 5 m/s^2.
Mark scheme
1 mark for F / m, 1 mark for 5.
Common mistake
Multiplying force by mass.
Exam tip
Rearrange F = ma to a = F divided by m.
Physics Year 11 Kinematics graphs Hard 2 marks
5. The diagram shows a velocity-time graph. Section A is a sloping line. What does it show?
t v A B
A Accelerationcorrect B Constant speedC StoppedD Moving backwardThe method
On a velocity-time graph, a slope means a changing velocity.
Worked solution
Section A slopes upward, showing the object is accelerating.
Mark scheme
1 mark for acceleration.
Common mistake
Reading a slope as constant speed.
Exam tip
A slope on a velocity-time graph means acceleration. A flat line means steady speed.
Physics Year 9 Density Hard 2 marks
6. A block has mass 60 g and volume 20 cubic cm. Work out its density in g per cubic cm.
Answer: 3
The method
Density equals mass divided by volume.
Worked solution
Density = 60 / 20 = 3 g per cubic cm.
Mark scheme
1 mark for the formula, 1 mark for 3.
Common mistake
Multiplying mass by volume.
Exam tip
Density = mass divided by volume. Keep the units consistent.
Physics Year 10 Electricity Hard 2 marks
7. A current of 2 A flows through a resistor with a voltage of 12 V across it. Work out the resistance in ohms.
A B C
Answer: 6
The method
Use the equation voltage equals current times resistance, rearranged.
Worked solution
R = V / I = 12 / 2 = 6 ohms.
Mark scheme
1 mark for V / I, 1 mark for 6.
Common mistake
Multiplying instead of dividing.
Exam tip
Rearrange V = IR to R = V divided by I.
Physics Year 11 Electricity and circuits Hard 2 marks
8. A device uses a current of 3 A at a voltage of 230 V. Work out the power in watts. Use P = V times I.
A B C
Answer: 690
The method
Power equals voltage multiplied by current.
Worked solution
P = 230 x 3 = 690 W.
Mark scheme
1 mark for V x I, 1 mark for 690.
Common mistake
Dividing instead of multiplying.
Exam tip
Power equals voltage times current for a simple device.
