force - A force can be a push or a pull, friction - a force that acts between two objects that are touching each other. It slows or stops movement between the two surfaces that are touching. For example - pushing a book along the floor, air resistance - an object experiences air resistance as it travels through the air - like a car or a ball or a cyclist, contact forces - These are forces that act when you are touching something (like pushing a supermarket trolley), gravity - the force that pulls objects towards each other and pulls everything towards the centre of the Earth. It is an invisible force (you can't see it), non-contact force - gravity is a non-contact force, interaction pairs - forces always act in pairs (two together), newtonmeter - you use this to measure a force, newtons - all forces are measured in newtons (s),
