Newton’s First Law
When a car or train starts suddenly, the passengers bends backward.
When a running horse stops suddenly, the rider bends forward.
When a coat/blanket is beaten by a stick, the dust particles are removed.
Newton’s Second Law ::
It is easier for a second law strong adult to push a full shopping cart than it is for a baby to push the same cart. Also, it is easier for a person to push an empty shopping cart than a full one.
Train wreck. If a train hits another train of equal force and speed, they will both go the same distance and feel the same force. But if the first train is hooked to a second, the single train will go twice the distance of the double train and will feel twice the force.
A bowling ball and a marble dropping at the same time.

Newton’s Third Law ::
When a bullet is fired from a gun with a certain force (action), there is an equal and opposite force exerted on the gun in the backward direction (reaction).
When a man jumps from a boat to the shore, the boat moves away from him. The force he exerts on the boat (action) is responsible for its motion and his motion to the shore is due to the force of reaction exerted by the boat on him.
The swimmer pushes the water in the backward direction with a certain force (action) and the water pushes the swimmer in the forward direction with an equal and opposite force (reaction).
The value of G is 6.67 x 10 11 Nm2/kg2.
The acceleration produced in a body due to force of gravity is called acceleration due to gravity (denoted as g) and its value 9.8 m/ s2
