Each worksheet can be printed out for use in class or viewed on mobile devices - they also include a set of answers and a video with explanations and how to approach that style of question. The pressure caused by a gas can be calculated using the equation: Worksheets to support all areas of GCSE Physics These are perfect for students to work through in lessons or independently at home. The force acting on the container due to these collisions is at right angles to the container.įor example, the collisions caused by a gas trapped inside a balloon cause forces to act outwards in all directions, giving the balloon its shape. These collisions may be between two particles, between a particle and the wall of the container, or between a particle and something else in the container. Since the particles in a gas are moving fast and randomly, collisions occur frequently. The smell of an air freshener can spread all around a room very quickly.
This means that it does not take long for a gas to spread out to fill its entire container. The speeds of the particles vary but, on average, they move quicker than they do in liquids and solids.
A simple electromagnet is made by coiling wire around an iron nail.Įlectromagnets are used in devices such as electric bells, and door locks that can be controlled remotely.The particles in a gas are moving very quickly in random directions.

The iron core increases the solenoid’s magnetic field strength. GCSE Physics (9-1) Revision Worksheets Past Papers ExamQA Free GCSE Physics revision materials. A solenoid, shown here in cross section, has a stronger electromagnetic field than a single straight wire ElectromagnetsĪ solenoid with an iron core is called an electromagnet. Unlimited access to the complete set of GCSE videos for 3 years for a one-off fee when you buy a Premium Plan. Everything organised for your exam board so you can find anything you need whenever you need it. The small magnetic fields caused by the current in each coil add together to make a stronger overall magnetic field. Hundreds of free video tutorials explaining physics in an easy and interesting way, with additional questions and resources. The field inside a solenoid is strong and uniform. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. This is often worded as every action has an equal and opposite. The strength of the magnetic field is greater:Ī solenoid consists of a wire coiled up into a spiral shape. According to Newtons third law of motion, whenever two objects interact, they exert equal and opposite forces on each other.
This magnetic field can deflect the needle of a magnetic compass. When a current flows in a wire, it creates a circular magnetic field around the wire. Jonny Nelson introduces an animated explanation of electromagnetism
