Document Summary
Inertia is the tendency for a body to resist changes in motion: mass is one of the main things that resists change. Mass is the quantity of matter in an object. It"s a scaler, meaning it has no direction and its symbol is m. Force: a push or pull acting on an object, it has a magnitude. You push with a certain amount of force: force is a lecture 4, body image & exercise, vector, since you push in a particular direction, point of application is also important. Where are you pushing on the object: symbol of a force is f, and it is measured in newtons (n) Internal forces: muscle force, joint force (ligament forces & bone on bone forces) External forces: gravity (weight, ground reaction force (friction between our foot & the ground, and the ground pushing up on us, friction.
