Edexcel IGCSE Physics – Equations Verified Guide
1. What does average speed represent?
- Average speed is calculated as the distance traveled divided by the time taken.
2. Define force in terms of its components.
- Force is the product of mass and acceleration, according to Newton's second law.
3. Explain acceleration in relation to changes in velocity.
- Acceleration is the rate at which velocity changes over time.
4. Define momentum and its components.
- Momentum is the product of mass and velocity of an object.
5. What is density and how is it measured?
, - Density is defined as mass per unit volume, calculated by dividing mass by volume.
6. How is efficiency calculated?
- Efficiency is determined by dividing useful energy output by total energy input.
7. Describe work done in terms of force and displacement.
- Work done is the product of force applied and the distance moved in the direction of the force.
8. Explain energy transferred and its relationship to work done.
- Energy transferred is equivalent to the work done.
9. Define kinetic energy and its formula.
- Kinetic energy is calculated as half of the mass multiplied by the square of velocity.
