State Newton's three laws of motion. Give one example of each.
Answers
Answer:
Newton has given three laws to describe the motion of bodies. ... A body at rest will remain at rest, and a body in motion will continue in motion in a straight line with the uniform speed, unless it is compelled by an external force to change its state of rest or of uniform motion.13-Nov-2018
Examples of Newton's 3rd Law: When you jump off a small rowing boat into water, you will push yourself forward towards the water. The same force you used to push forward will make the boat move backwards. When air rushes out of a balloon, the opposite reaction is that the balloon flies up.
1&2 Law example :
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer:
Newton's First Law OF Motion:
An object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it.
Examples:- If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goal post.
Newton' Second Law OF Motion:
The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force.
Examples:- It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the full shopping cart.
Newton's Third Law OF Motion:
Every action force has an equal and opposite reaction force which acts simultaneously.
Examples:- When air rushes out a balloon,the opposite reaction is that the balloon flies up.
