TOPIC 5: SIMPLE MACHINES | PHYSICS FORM 1 Simple Machines A simple machine is a non-powered mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. A simple machine uses a single applied force … Read more
TOPIC 4: FORCES IN EQUILIBRIUM | PHYSICS FORM 1 Moment of a Force The Effects of Turning Forces Explain the effects of turning forces A force is a push or pull which when applied to a body it will change its state either by stopping it if it was in motion or making it move if it … Read more
TOPIC 3: MAGNETISM | PHYSICS FORM 1 Concept of Magnetism The Origin of Magnetism Explain the origin of magnetism Chinese were the first to use the metal magnetite called lodestone. A Lodestone was capable of attracting small iron pieces and it was used as a crude navigation compass by Greeks. Lodestones were the earliest magnets. Iron, nickel … Read more
TOPIC 2: CURRENT ELECTRICITY | PHYSICS FORM 2 Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the … Read more
TOPIC 1: STATIC ELECTRICITY | PHYSICS FORM 2 Concept of Static Electricity The Concept of Static Electricity Explain the concept of static electricity Static electricity refers to the electric charges stored on a conductor. The Orign of Charges Explain the origin of charges When a plastic pen is rubbed with a cloth, it acquires the … Read more
TOPIC 9: LIGHT | PHYSICS FORM 1 Sources of Light The Concept of Light Explain the concept of light Light can carry both energy and information. It both is the way the sun delivers energy to the world, making life possible, and it is a very important way that we learn about the world, through … Read more
TOPIC 8: WORK ENERGY AND POWER | PHYSICS FORM 1 Work The Concept of Work Explain the concept of work If a person pushes a wall and the wall does not move, though the person may sweat and physically become tired, he would not have done any work. But if the person pushes a trolley … Read more
TOPIC 7: PRESSURE | PHYSICS FORM 1 Concept of Pressure The Concept of Pressure Explain the concept of pressure Pressure is defined as the force per unit area. OR Pressure is the force acting normally (perpendicularly) per unit surface area. It is calculated by the formula: Pressure = Force (f)/Area (A) P = F/A Where … Read more
TOPIC 6: STRUCTURE AND PROPERTIES OF MATTER | PHYSICS FORM 1 Structure of Matter State of matter is defined in terms of the phase transitions which indicate the change in structure and properties. Solids, liquids and gases all are made up of microscopic particles. The behavior of all these particles also varies in three phases. The … Read more
TOPIC 5: ARCHIMEDES’ PRINCIPLE AND LAW OF FLOTATION | PHYSICS FORM 1 Archimedes’ principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. The Concept of Upthrust Explain the concept of … Read more
