What is the simplest way to explain newtons 3 laws of motion.?

Answer 1

I will list and then describe each law, hopefully it will be simpler

1. An object in motion stays in motion and an object at rest stays at rest unless acted upon by an outside force.

This is known as the law of inertia, or the law of balance, since it describes balance in motion.

2. Force equals mass times acceleration.

This law shows how you go about disturbing the balance in motion, which is by applying an acceleration to a mass to create a force.

3. For every action there is an equal and opposite reaction.

This law describes how motion goes back to balance by having an opposite and equal reaction to counter the force.

So, simply put:

1. Balance.

2. Balance Upset.

3. Balance Restored

In other terms:

1. Equilibrium.

2. Unbalanced Forces.

3. Balanced Forces.

And there you go.

Answer 2

If you are at rest, you need to push yourself or be pushed by someone else to start moving. This is the first law and inertia is the property. Another example is that a fan continues to rotate after the power is switched off but stops eventually due to friction.

The more the mass of a body, the higher should be the force to make it accelerate. A small car and a large truck need engines of different sizes to make them go.This is the second law.

For every action there is an equal and opposite reaction. When you fire a rifle with the butt against your shoulder, you experience the recoil. Similarly if you stand in a boat and throw stones forward, the boat moves backwards. You need to row in the direction opposite to the direction in which you want to move, when you are in a boat. This is the third law of motion.

Answer 3

1. Show the video of any of the space capsules in flight in zero gravity.

The first law (a body remains at rest or in uniform motion in a straight line unless acted on by a force) is quite nicely demonstrated by an astronaut pushing a stationary object which moves at a steady speed until it hits another object

2. Use an air track to measure the motion of an object of known mass, this will fairly closely show the second law that the acceleration of a body acted on by a force is equal to mass x acceleration

3.Use a block of wood on a rough surface and attach a spring balance to it. Apply a force to the spring balance and the object will not move thus showing that friction is creating an equal and opposite force to the one applied on the spring balance. The third law says to every action there is an equal and opposite reaction

Answer 4

The second law tells what a force is and does: F=MA "Force equals mass times acceleration." Or, as Newton wrote it: Change in momentum=FXtime elapsed.

Answer 5

For every action force, there is an equal and opposite reaction force.

When you slap someone, your palm feels a force that is equal to that which with you've applied on that someone.

2 people are on roller blades facing each other. When they come closer towards each other and pushes palm to palm, they will both move back by an equal force.

Answer 6

When you stand against a wall and push, it is pushing you with the same amount of force as you are pushing it.

Answer 7

Bang your head onto a brick wall.
The harder you hit it(action force), the more your head is hurt by it (reaction force).

Answer 8

Use a snooker or pool table and two balls.
