Can you give me a few examples of newton's second law of motion?

Question

Examples of Newton's second law of motion

Minimum of TWO(2)

Answer 1

There are a lot of examples: each process which needs force (that's almost every process in - classical - physics) is described by newton's second law.

The force which is needed to accelerate a car from 0 to, lets say, 100km/h must be caluclated with F = m*a.

The force which affects on a mass which falls from any height on the floor is caluclated by F=ma, wheras a is - in this case - the acceleration of gravity, called g.

The force which presses you in the seat of your car when you accelerate / or which presses you against the wheel when you slow down is calculated by F=ma.

That's the meaning of this formula: every force which affects on a body is caused by the mass of the body and its changing of velocity.

Answer 2

Newton's second law is best described in the equation "F=m*a", Force equals mass times acceleration. This can also be written as "F/m=a", which shows that the acceleration of an object depends on the (net) Force and the mass.

Consider this: I f you push on a 20 kilogram box, the acceleration will depend on how hard you push. The harder you push, the higher the acceleration. Conversely, if you push on boxes of varying masses with the same force of, say, 10 Newtons, the more massive the box, the lower the rate of acceleration. This illustrates Newton's second law by showing how acceleration varies directly with force and inversely with mass.

Answer 3

In a vacuum or on a frictionless surface:

If you move a block with a mass of 10 Kg with a force of 10N, it will accelerate faster than a block with a mass of 20 Kg moved with the same force.

Second example: keep the masses the same, but use different forces. I think you can figure out the rest.
