What is the application of first law of motion?
The First Law states, “A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.” This simply means that things cannot start, stop or change direction all by themselves.
It requires some force acting on them from the outside to cause such a change..
What is Second Law of Motion for Class 9?
Newton’s Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. ie., F=ma. Where F is the force applied, m is the mass of the body, and a, the acceleration produced.
What is the application of Newton’s second law of motion?
Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force.
What is a real life example of Newton’s second law?
5. Examples of Newton’s 2nd Law If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. 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.
