October 24 (Thursday) Action-Reaction
Unit 3 Objective Sheet
Today was a day of demonstrations...whose purpose was to start understanding Newton's 3rd Law better.
Newtons 3rd Law .... For every action there exists an opposite and equal 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. website explanation
