Physics Formulas for IGCSE test
| Term | Formula |
|---|---|
| Speed | Distance / Time |
| Velocity | Frequency X Wavelength |
| Acceleration | (initial speed - final speed) / (initial time - final time) |
| Density | Mass / Volume |
| Force | Mass x acceleration |
| Power | Work done (or energy transferred) / Time |
| Pressure in liquids | Density x gravity x height |
| Gas constant | Pressure x volume (at constant temperature) |
| energy | Voltage x Current x Time |
| Kinetic Energy | ½ x mass x velocity(squared) |
| Gravitational Potential Energy | Mass x gravity x height |
| Work done | Force x distance moved in direction of force |
| Specific Latent Heat | Energy supplied / Mass changing state |
| Specific Heat Capacity | Energy supplied / Mass x Temperature rise |
| Heat Capacity | Energy supplied / Temperature rise |
| Refractive Index | Speed of light in vacuum / Speed of light in medium |
| Refractive Index | Sin i / Sin r |
| Resistance | Voltage / Current |
| Resistors in series | Rs = R1 + R2 |
| Resistors in parallel | (1 / R) = (1 / R1) + (1 / R2) |
| Current | Charge / Time |
| Moment | Force x perpendicular distance from point |
| Spring Force | - Spring constant x spring displacement |
| Power | Voltage x Current |
| Pressure | Force / Area |
