IGCSE Physics worksheets | GCSE Physics problems | Physics questions – worksheet

This post contains problems and questions covering GCSE physics and the IGCSE physics syllabus. These are compiled from GCSE Physics Specimen Assessment Materials. These are equally helpful to prepare for other boards and competitive examinations of different countries.

If you need the formula sheet or physics notes to refer to while attempting the worksheet below, you may browse through this Blog site to find related study material.

Use the search facility available on the pages. Also, I am going to add relevant links beside the worksheet questions, those will lead you to the relevant posts on this site.

IGCSE Physics worksheets | GCSE Physics problems & Questions

 1 ] A car is pulled forward and begins to move along a road in the direction shown below. After a few seconds the car is moving at a constant speed of 2m/s. Label clearly the two horizontal forces acting on the car.

What can you say about the size of these two forces? _________________

The car then accelerates forward along the horizontal road. It takes 3seconds to increase its speed from 2m/s to 20m/s. Calculate the acceleration (rate of change of speed).

You are advised to show clearly how you get your answer.

Acceleration = ________________m/s^2

5] To study the motion of a ball down a curved runway the apparatus shown below was set up. The ball is released at various points along the runway. The height above the table at each point is H. When it reaches the bottom it travels through the air and the point where it hits the floor is marked. The distance S from the bottom of the table to this point of impact is measured.

For each value of H the ball was released three times and the value of S in each case recorded. The measurements of the height H and the distance S were taken and are shown in the table below.

(a) Using the data given in the table calculate the average value of S for each height H. Write your answers in the spaces on the table. You may use the space below for your calculations. Two values have been calculated for you.


6] (a) A car sits at rest at the top of a roller coaster ride as shown in the diagram below. The brake is released and the car travels down the slope.

(i) On the diagram mark and label two forces acting on the car when it is moving.

(ii) At the bottom of the slope the car reaches a speed of 27m/s and continues along a horizontal track in which a braking system is operated. The deceleration of the car is 6m/s2. Calculate the time taken to come to rest. You are advised to show clearly how you get your answer. Time taken = ________________seconds .

(iii) The mass of the car is 1000kg. The force applied to the car by the braking system is 5000N. Calculate the additional frictional force provided by air resistance which brings the car to rest. You are advised to show clearly how you get your answer. Additional Frictional Force = ________________N


7] A sky diver jumps from an aircraft and for a time falls through the air without her parachute open. After a time she opens the parachute. The graph below shows how the velocity of a skydiver changes as she falls through the air. Her parachute opens at the time marked.

Describe and explain how her acceleration changes as she descends. You should concentrate on the periods OA, BC and DE. In this question you will be assessed on your written communication skills including the use of specialist science terms.

8] The diagram below shows a fish in a pond. A person looking into the pond sees the fish not at its true position but at the position shown in the diagram.

Complete the diagram to show how the man sees the fish. Draw an arrow on the given ray to show its direction.

9] The diagram shows a ray of white light being dispersed by a triangular glass prism.

(i) On the diagram label the two colours at the top and bottom of the spectrum.

(ii) Explain, in detail, how this spectrum is produced by the prism. In this question, you will be assessed on your written communication skills including the use of specialist science terms.
