Document Summary

V is distance per time or d/t: so the units are distance/t^2 or m/s^2. The science of life: experiencing extreme acceleration, the jet engine was introduced by the germans in world war ii, simple design but very powerful. If reactions are not equal and opposite there is movement: ex. Gravity is always pulling down, normal force pushes up against it which allows a person to sit in a chair without falling: forces act in pairs. Momentum (2. 4: motion: depends on mass and speed, linear momentum- p (greek letter rho, p=m*v, law of conservation of linear momentum, angular momentum and regular momentum are also conserved. Linear momentum: we can consider a mass traveling at a velocity, momentum units are therefore: kg*m/s. If no external force is applied to the moving mass, it will have the same momentum potentially forever: thus momentum is a conserved property.
