forces 0.0 / 5 ? PhysicsForcesGCSEAQA Created by: Abby RadcliffeCreated on: 05-10-17 10:54 what is a vector quantite? A vector quantite have a magnitude in size and a direction. 1 of 11 what are forces caused by? A force is an object that interacts with each other. 2 of 11 what happens when you apply a force to an object? When you apply a force too an object you can cause it to deform,stretch,compress or bend. 3 of 11 when a force stretches or compresses an object. This causes energy to be transeferred to the elastic potential energy store of the object. 4 of 11 what happens when you push something along a rough surface? when you push an object over rough surface you are doing work against frictional forces. 5 of 11 what is the names of an unstretched string? When a spring is unstretched it is sometimes called a spring's natural length. 6 of 11 You can calucualte the weight of an object if you know its mass, strength and gravitational field Weight(N)=Mass(KG)*Gravitional Field Stregth (N/KG) 7 of 11 what happens when the graph is a straight line? when the graph is a straight line there is a linear relationship between force and extention. 8 of 11 If an object has been elastically deformed it can go back to its original shape and length after the force has been removed. 9 of 11 contact force examples friction,air resistance,tention and normal contact force 10 of 11 Non-contact force examples magnetic force, gravitional force and electrostatic force 11 of 11
