Newton's three laws of motion explain how objects move under force. They are the foundation of classical mechanics and common in exams.
Work, energy and power are linked physics concepts. Work is done when force moves an object, and energy is the capacity to do work.
Gravitation is the force of attraction between all objects with mass. Newton's law of gravitation explains the motion of planets and falling bodies.
Light is a form of energy that lets us see. Reflection and refraction explain how light bounces off and bends through different media.
Sound is a form of energy produced by vibrations. It needs a medium to travel and shows properties like reflection, pitch and loudness.
Electricity is the flow of charge and magnetism is the force of magnets. Together they form electromagnetism, used in motors and generators.
Heat is a form of energy that flows from hot to cold bodies. Temperature measures the degree of hotness or coldness of an object.
Matter exists mainly in three states: solid, liquid and gas. Each has its own shape, volume and arrangement of particles.
