PhysicsDistance, displacement, speed and velocityGCSEEdexcel Created by: emj790Created on: 25-02-17 10:14 What must it have to be a vector? Magnitude (size) and a direction 1 of 30 Lots of __ are vector quantities Physical quantities 2 of 30 Give some examples of vector quantities (6) Force, velocity, displacement, weight, acceleration, momentum, etc. 3 of 30 What must it have to be scalar? Magnitude (size) and no direction 4 of 30 Give some examples of scalar quantities (6) Speed, distance, mass, energy, temperature, time, etc. 5 of 30 What is distance, scalar or vector? Scalar 6 of 30 What is displacement, scalar or vector? Vector 7 of 30 What is distance? How far an object has moved 8 of 30 What does displacement do? It measures the distance and direction in a straight line from an object's starting point to its finishing point 9 of 30 If you walk 5m north and then 5m south, what is the distance and displacement? The distance is 10m and the displacement is 0m 10 of 30 What is speed, scalar or vector? Scalar 11 of 30 What is velocity, scalar or vector? A vector 12 of 30 What do speed and velocity measure? How fast you're going 13 of 30 What is speed? How fast you are going without any regard to direction 14 of 30 Give an example Something along the lines of: 30mph or 20m/s 15 of 30 What is velocity? It is speed in a given direction 16 of 30 Give an example Something along the lines of: 30mph north or 20m/s, 060degrees 17 of 30 Due to the difference, what does this mean you can have at constant speed? You can have objects travelling at a constant speed with a changing velocity 18 of 30 When would this happen? When the object is changing direction whilst staying at the same speed 19 of 30 What is the equation for distance, speed and time? speed= distance/time 20 of 30 What rarely happens? Objects travelling at a constant speed 21 of 30 This means what normally? That your speed is always changing 22 of 30 What is the typical speed for walking? 1.4 m/s (5km/h) 23 of 30 What is the typical speed for running? 3 m/s (11km/h) 24 of 30 What is the typical speed for cycling? 5.5 m/s (20km/h) 25 of 30 What is the typical speed for cars in a built-up area? 13 m/s (47km/h) 26 of 30 What is the typical speed for cars on a motorway? 31 m/s (112km/h) 27 of 30 What is the typical speed for trains? Up to 55 m/s (200 km/h) 28 of 30 What is the typical speed for wind speed? 5-20 m/s 29 of 30 What is the typical speed of sound in air? 340 m/s 30 of 30
