Newton s 3rd law
For every action, there is an equal and opposite reaction
.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
Force Depends on Time: F=F(t)
Assuming that the motion is one-dimensional, Newton's second law is written as the second order differential equation: md2xdt2=F(t). Integrating once, we find the velocity of the body v(t): v(t)=v0+1mt∫0F(τ)dτ
Answer:
3rd law-- Every action there is an equal and opposite reaction....
2nd law-- The rate of change of momentum is proportional to the applied force in the direction of the force..
