PhysicsForces and MotionIGCSEEdexcel Created by: sophie_kkCreated on: 11-12-19 19:11 what is force a vector quantity because it has size and direction 1 of 11 reaction force the upwards push on an object from the ground 2 of 11 weight downward pull of gravity on an object 3 of 11 friction opposes motion 4 of 11 how do we measure force? using newtons (N) 5 of 11 what will a force of one newton do? will make a mass of one kilogram accelerate at one metre per second squared 6 of 11 what are magnetic forces used for? make electric motors rotate, gold fridge doors shut 7 of 11 upthrust upward push of the surrounding air/liquid on an object 8 of 11 resultant force the total of all the forces acting on an object 9 of 11 transfer in friction of a moving object kinetic energy is transferred as heat as work is done by the friction force 10 of 11 when does friction occur? occurs when solid objects rub against other solid objects and also when objects move through fluids (liquids and gases) 11 of 11
