Magnets & Electromagnets Exam Content
What's included
The Waves section in the AQA Physics specification covers the properties and behaviors of waves, including both transverse and longitudinal types. Students learn about key wave characteristics such as amplitude, frequency, wavelength, and speed, alongside the wave equation for calculating these properties. The section explores how waves interact with materials through processes like reflection, refraction, and diffraction, as well as the principles behind interference patterns. It also covers the electromagnetic spectrum, detailing uses for various wave types, and examines sound waves, including how they travel and their applications in technologies like ultrasound. Practical experiments, such as measuring wave speeds and observing wave behavior in different media, reinforce these concepts, blending theoretical understanding with hands-on skills.

Forces Exam Content
What's included
The Forces section of the AQA Physics specification covers a range of key concepts related to motion, interactions, and the effects of forces. It includes scalar and vector quantities, Newton’s laws of motion, and the relationship between force, mass, and acceleration (F=ma). Students learn about resultant forces, free body diagrams, and the principles of work done and energy transfer. The topic also explores elasticity, including Hooke’s Law, and investigates pressure in fluids and atmospheric pressure. Concepts of momentum and collisions are introduced, along with the importance of conservation of momentum. The section also covers circular motion, gravitational forces, and the effects of friction, drag, and terminal velocity. Additionally, it includes moments, levers, and gears, showing how forces can be applied in mechanical systems.
Space Exam Content
What's included
The Space Physics section of the AQA Physics specification covers key concepts related to the universe and celestial bodies. It includes the life cycle of stars, from nebulae to black holes or neutron stars, and the formation of elements through nuclear fusion. Students learn about the solar system, including the structure of planets, moons, and artificial satellites, and explore the differences between orbital motion and gravitational fields. The Big Bang Theory and evidence for the expansion of the universe, such as redshift and cosmic microwave background radiation, are also covered. Additionally, the topic includes the role of satellites in communication and observation, and the forces acting on objects in space.
