contact force when two objects hit or bump into each other (friction)
inertia objects want to resist motion (at rest stays at rest in motion stays in motion)
Action-at-a-distance force when two forces act on each other but don't touch or bump (gravity) (magnets repealing)
newtons 1 law Something at rest stays at rest and something in motion stays in motion (law of inertia)
newtons 2 law the force needed to move an object depends on mass and acceleration (when moving with more force it will go faster)
for every action there has to be a equal and opposite reaction
net force a combination of forces acting on a object
units for force newtons
units for acceleration M/S squared
formula for force F=ma
calculation of net force 1v+2v=3v same direction add different subtract
