CIE IGCSE Physics Equations For Guaranteed Success

CIE IGCSE Physics Equations For Guaranteed Success 1. Define speed. - Speed is the distance traveled per unit of time. 2. Define acceleration. - Acceleration is the change in velocity per unit of time. 3. Define velocity. - Velocity is the displacement per unit of time. 4. Define weight. - Weight is the gravitational force acting on an object, calculated as mass multiplied by gravitational acceleration. 5. Explain Hooke's Law in terms of force. - According to Hooke's Law, the force exerted by a spring is proportional to its extension. 6. Explain Newton's Second Law in terms of force. - Newton's Second Law states that force is equal to mass multiplied by acceleration. 7. Define moment. - Moment is the product of force and the perpendicular distance from a pivot point. 8. Define kinetic energy. - Kinetic energy is the energy possessed by an object due to its motion, calculated as half of mass multiplied by the square of velocity. 9. Define gravitational potential energy. - Gravitational potential energy is the energy stored in an object due to its position above the Earth's surface, calculated as mass multiplied by gravitational acceleration multiplied by height. 10. Define efficiency. - Efficiency is the ratio of useful energy output to total energy input. 11. Define work done. - Work done is the product of force and the distance over which the force acts. 12. Define power. - Power is the rate at which work is done or energy is transferred, calculated as
