1.	State Newton's third law. Explain it with three examples.
Answer» SOLUTION :Newton.s third law of motion : Newton.s third law states that .for every action, there is an equal and opposite reaction. They always act on two different bodies.. If a body A applies a force `F_(A)` on a body B, then the body B reacts with force `F_(B)` on the body A, which is equal to `F_(A)` in magnitude, but opposite in DIRECTION. `F_(B)=- F_(A)` Examples: (i) When birds fly they push the AIR downwards with their wings (Action) and the air pushes the bird upwards (Reaction). (ii) When a person swims he pushes the WATER using the hands backwards (Action), and the water pushes the swimmer in the forward direction (Reaction). (iii) When you fire a bullet, the gun recoils backward and the bullet is moving forward (Action) and the gun EQUALISES this forward action by moving backward (Reaction).
