| Question | Answer |
| What is Displacement? | Where you end up? |
| What is distance? | The length you travel |
| What is Speed? | Speed is considered to be the time taken for an object to cover a particular distance |
| How is Distance measured | Kilometers Metres |
| How is time calculated | Hours Seconds |
| How is Average Speed calculated | Average speed = Total distance –––––––––––––– Total time |
| What is Velocity? | Velocity is the rate at which an object changes its position Example: Velocity = 55km/hr, east |
| What is Scalar Quantity? | How much 'ground' an object has covered during its motion |
| What is a Vector Quantity? | How far an object has moved from its original position |
| How do you convert distances? | |
| Converting times | Hours - Minutes - Seconds |
| Formulas | s Velocity: V= ––— t Average distance: s = v x t s Time: t = ––––— v |
| A.) The Student is stationary (not walking) | |
| B.) The Student is walking away from her home | |
| C.) The Student is walking away from her home and stops for a rest | |
| How do you calculate Velocity? | s Velocity: V= ––— t |
| How do you calculate average distance? | Average distance: s = v x t |
| Which units can be used to calculate speed? | m/s km/h km/s |
| How do you calculate distance? | S = V(av) x t |
| How do you calculate acceleration? | Vf - Vi Acceleration = ————–– time |
