Title: Physics / Topic 2: Mechanics / 8: Newtons Laws of Motion

Q: What are Newtons 3 Laws of Motion?
A: 1. An object will remain at a constant velocity unless acted on by a resultant force
2. The resultant force is equal to the rate of change of momentum \(F^{(N)}=m^{(kg)}×a^{(ms^{-2})}\)
3. If object A exerts a force on object B, then object B will exert an equal and opposite force of the same type on object A

Q: State two ways in which forces in a pair differ
A: - Opposite direction
- Act on different bodies

Q: State two ways in which forces in a pair are identical
A: - Same magnitude
- Same type (push/pull)
