PhysicsAllGCSEAQA Created by: iiCrystal15Created on: 13-06-19 14:30 Define Scaler quantity It is just a number 1 of 14 Define a Vector quantity It is just a number and direction 2 of 14 What is an example of a contact force Push and pull is an example of a contact force. 3 of 14 What is an example of a non contact Force Weight 4 of 14 How do you calculate the resultant force? It is the sum of all the forces added together 5 of 14 What is the difference between Mass and weight? Mass will always stay the same, weight depends on gravity 6 of 14 What equation link mass, weight and gravity? W=M * G 7 of 14 What are the important units? N=Weight, KG= Mass, J= Work, M= Distance, N= Force 8 of 14 What equation linking, work, force and distance? W= F*D 9 of 14 What equation links force, Spring constant and extension? F=KE 10 of 14 What equation linking elastic potential energy, spring constant and extension Ee= 0.5KE^2 11 of 14 What is a fluid? A fluid can be a liquid or a gas. 12 of 14 Can a fluid be compressed? A liquid cannot be compressed but a gas can be compressed. 13 of 14 What equation links force, area and pressure? P= Force over area.. F/A 14 of 14
