## Resource summary

 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
