P5b - Vectors and Equations of Motion 3.0 / 5 based on 2 ratings ? PhysicsEquations and FormulaeGCSEOCR Created by: natalie27Created on: 25-11-13 17:04 Quantities that have a size only e.g. mass, energy and speed. Scalar 1 of 8 Quantities that have a size and a direction e.g. velocity, force, and acceleration, have size and direction. Vector 2 of 8 How fast an object is moving at a particular time. Direction is not important when measuring this. It is a scalar quantity. Speed 3 of 8 How fast an object is moving in a particular direction. This is a vector quantity. Velocity 4 of 8 E.g. if two cars are travelling along a road, their motion can be described in terms of their ________ speed. Relative 5 of 8 The direction travelled in a given direction. Displacement 6 of 8 Equations used to calculate velocity and direction. SUVAT 7 of 8 If two forces are acting at right angles on the same object, you can work out the _________ force using Pythagoras' Thereom. Resultant 8 of 8
