TOPIC 2: FRICTION | PHYSICS FORM 3 Concept of Friction The Concept of Friction Explain the concept for friction Friction is the force which opposes (resists) motion of the body for example: If a block of wood is placed on a table it remains at rest Unless it is acted upon by an external force. … Read more
TOPIC 1: APPLICATION OF VECTORS | PHYSICS FORM 3 Scalar and Vector Quantities Difference between Scalar and Vector Quantities Distinguish between scalar and vector quantities Scalar Quantities These are physical quantities which have magnitude only. Examples of scalar quantities include mass, length, time, area, volume, density, distance, speed, electric current and specific heat capacity. Vector … Read more
TOPIC 9: SUSTAINABLE ENERGY RESOURCE | PHYSICS FORM 2 Sustainable energy, specifically renewable energy or green energy, is an energy source which can be replenished, that is essentially inexhaustible. Sustainable sources of energy include solar, wind, water, biomass and geothermal. Non renewable energy sources include coal, oil and natural gas. Water Energy The Generation of … Read more
TOPIC 8: TEMPERATURE | PHYSICS FORM 1 Concept of temperature The Term Temperature Define the term temperature Temperature is property of a body, which decides which way heat will flow when it is placed in contact with another body. The SI Unit of Temperature State the SI unit of temperature Temperature refers to the degree … Read more
TOPIC 7: NEWTON’S LAW OF MOTION | PHYSICS FORM 1 1st law of Motion The Concept of Inertia Explain the concept of inertia Inertia is the ability of a resting body to resist motion or a moving body to continue moving in a straight line when abruptly stopped. The more mass a body has, the … Read more
TOPIC 6: MOTION IN STRAIGHT LINE | PHYSICS FORM 1 Motion In Straight Line Motion is the change of position of an object from one place to another. There are two types of motions; i.Circular motion-Is the motion of an object in a circle. Examples; a/. motion of the electron around the nucleus of an … Read more
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
