Newton's Laws
- Newton's first law
- Inertia-a measurement of how hard it is to move a mass
- more mass=more inertia
- Law of inertia
- objects at rest tend to stay at rest, objects in motion tend to stay constant in motion unless a force acts against
- Newton's second
- force=mass x acceleration
- A=F/M
- Newton's third law
- For every action there is an equal and opposite reaction
- RESULTANT FORCE
- Other forces
- forces on the road
- stopping distance=thinking + breaking distance
- vectors and scalars
- scalars=size (ex:mass)
- vectors=direction and size(velocity)
- resultant-vector sum of 2+ vectors
- weight=mass x gravity(10)
- 1kg=10N
- pyhagorean theorem to find res. force
- sOh - cAh - tOa
- sin,tan,cos-1 to find angle
