Physics Paper 2 (GCSE)
1. Work done equation: force x distance
2. Change in Gravitational Potential Energy: mass x gravitational field strength x
change in vertical height
3. Kenetic energy equation: 1/2 x mass x velocity^2
4. Power: energy transferred/ time - amount of work done or energy transferred per
second- watt (W)
5. Efficiency equation: Useful Energy / Total Energy Input
6. Scalar: A physical quantity that has magnitude only (just a number)
7. Scalar examples: speed, mass, distance, time, energy
8. Vector: A quantity that has magnitude and direction
9. Vector examples: displacement, velocity, acceleration
10. Series circuit: An electric circuit with a single path
11. Resultant force: mass x acceleration overall force on a point or an object
(if forces act in same directions +, different -)
12. parallel circuit: A circuit that contains more than one path for current flow.
13. Charge (Q): current x time - value of electricity flowing through a circuit
14. Current (I): charge = current x time the rate of flow of electrons - amps
, 15. potential difference (V): current x distance the driving force that pushes the
charge around - volts (V)
16. Current in a series circuit: Is the same everywhere
17. Current in a parallel circuit: Is shared between branches
18. Resistance in a series circuit: adds up
19. Resistance in a parallel circuit: total resistance is lower than the smallest
single resistor
20. Potential Difference in series circuit: Shared between components
21. Energy definition and equation: Charge x Potential difference - the capacity for
doing work - Joules
22. Energy equation: current x pd x time
23. Power equation 1: energy/time
24. Power equation 2: pd x current
25. Power equation 3: current^2 x resistance
26. Main electricity in UK: 230 V / 50 h
27. Alternating current: - found in mains - alernating voltage
28. Direct current: - found in batteries - has consistant voltage
29. magnetic materials: iron, cobalt, nickel
30. Thermistor: A resistor that changes its resistance with a change of temperature.
31. LDR: Light dependent resistor
