What is a Newton? An Explanation

Рет қаралды 147,052

Күн бұрын

This video goes over an explanation of the metric unit for force which is the newton. The newton is the derived unit in the metric system for force. A force is a push or a pull. One newton is equal to the force that would give a one kilogram mass an acceleration of one meter per second squared. A 100 gram mass exerts a gravitational force of one newton. The newton is named after Sir Isaac Newton who lived from 1642 until 1727.
Subsequent videos will cover the joule and the watt. The joule is the metric unit for work and energy. Work is done on an object or energy is transferred to an object when a force is applied to it through a distance. The watt is the metric unit for power. Power describes how fast work is done.

The first one is an object at rest will stay at rest and an object in motion will stay in motion Second is force is mass times acceleration Third every action has an equal and opposite reaction Fourth one maybe is the force of gravity is directly proportional to the product of their masses and inversely proportional to the square of the radius of the orbit

Doesn't F=ma apply only in certain situations? If I am exerting pressure on a wall and the wall doesn't move, there is no acceleration and my mass probably doesn't matter either. If I am applying a force of 10N to the wall, how would you calculate that using my mass of 80kg and acceleration = 0?

@stepbystepscience 4 жыл бұрын

F = ma applies is every situation, except for quantum mechanics. The mass would be the mass of the wall, F is the net force (the sum of all the forces acting on the wall) applied to the wall and a is of course the acceleration. If you pushed on the wall with a force of 10 N, then the wall pushes back in the opposite direction with a force of 10 N. The sum of these two forces is 0 N (+10N + -10N = 0N) and therefore the acceleration of the wall is 0 N and it does not move. Does that help?

@markp805 4 жыл бұрын

@@stepbystepscience Sorry that does not help especially since you didn't answer the question. It makes sense that if we say that NET F = ma. But you didn't say or imply that. Disregarding QM, you repeated that in all situations, f=ma, not NET f=ma, which I would understand. I might have 100 different vectored forces and the beauty of F=ma appears to be that we can calculate the Net force of those 100 different forces, simply by using the mass of the object and it's current acceleration. Thank you Newton, Simply genius. However, that does not explain how to use mass and acceleration to calculate one of the vectored forces on the object. By definition, 1 Newton of Force is the Force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. Doesn't this simply mean a 1N of force is EQUIVALENT to a 1Kg mass accelerating at one metre per sec/sec. If you wanted to say the 10N force I am applying is equivalent to a force of 10kg accelerating at 1m/s/s, that is accurate, but how can you calculate the vectored 10N force using f = ma when my mass is 80kg and my hand against the wall is not moving? Please calculate the force I am applying using f = ma.

I assume you are referring to the units for acceleration, m/s2. A bit hard to explain here but, acceleration is the change in velocity over time. So it is your change in m/s per s which turns out to be m/s/s which is m/s2.
