- 1Formula for an unbalanced Forcef = ma
- 2Formula for accelerationa = (v-u) / t
- 3Formula for momentump = mv
- 4Formula for impulseF = mv - mu / t
- 5Formula for Hooke's lawF = -kx
- 6The last point at which it obeys Hooke's lawLimit of proportionality
- 7The last point at which the object will return to it's original length when the force is removedElastic limit
- 8The point at which the structural integrity of the material breaks down and permanently deformsYield point
- 9Unit for forceNewton (N)
- 10Vectorsquantity that is described by both size (distance) and direction
- 11Scalersquantity that is only described by magnitude (e.g. temperature)
- 12unit for accelerationm/s^2
- 13definition of accelerationthe rate of change of speed
- 14Newton 1An object at rest remains at rest and an object in motion remains in motion in a straight line, at a steady speed unless acted upon by an unbalanced force
- 15Newton 2f = ma
- 16Newton 3If object A exerts a force on object B, then object B exerts an equal and opposite force on object A
- 17definition of terminal velocitywhen something can't increase in acceleration anymore (drag = weight)
