3 examples of each laws of motion according to newton?

Answer 1

First law: (1) The book rests on the table. It doesn't move. (2) In my car, I stop pressing the gas pedal, and the clutch. The car continues to move for quite a while. (However, there is some friction, so this is not a perfect example.) (3) Objects in outer space are better examples of movement without friction. They can continue going on, for a long, long time.

Second law: A setting with little friction is convenient for illustration. (1) If I push a child on a swing, the swing starts moving. (2) If I push a grown-up on the same swing, the same push makes the grown-up move less (less acceleration).

Third law: (1) If I jump out of a canoe, the canoe will start to move back. (In fact, if the canoe is light, this can make me mis-calculate the jump, and fall in the water, instead of jumping on land.) (2) If I fire a gun, the bullet is propelled out of the gun - and the gun pushes back against my shoulder. This can be quite painful if you are prepared for it.

Answer 2

1. First Law: An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force. For example, a book on a table will not move unless pushed.

2. Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. For example, a heavier object requires more force to accelerate than a lighter object.

3. Third Law: For every action, there is an equal and opposite reaction. For instance, when a person walks, their foot exerts a force backward on the ground, while the ground exerts an equal force forward on the person's foot.
