# 7 Best Newton’s third law Examples

Newton’s third law of motion is all about understanding these two terms:

1. Action

2. Reaction

If you understand these two terms properly, you’ll definitely understand the whole statement of newton’s third law of motion.

Now, read the statement of Newton’s 3rd law of motion mentioned below.

Newton’s third law of motion states that:

“To every action, there is always an equal and opposite reaction”

Before moving on Newton’s third law examples, take a look at these 3 points:

(This will make you understand Newton’s third law examples in a more easier way)

All Newton’s third law examples must satisfy these 3 points.

## Newton’s third law examples

Don’t worry. (If you have not understood the above points)

I’ll make this simple.

Let’s understand the above points with Newton’s third law examples, so you’ll get an exact idea.

### #1 Missile launch

How Newton’s third law of motion works when a missile is launched?

Look:

According to Newton’s third law of motion,

“To every action, there is always an equal and opposite reaction”

Let’s make it simple.

Simply think, what happens when a missile is launched?

When the fuel burns in the engine, it creates an upward thrust which pushes the rocket forward, right.

Now the question is,

How will you show the action and reaction force pairs?

See this,

When a missile is launched, a large amount of fuel burns and comes out in the downward direction.

This is known as action force.

At the same time,

This exhaust gas creates an upward thrust which helps the rocket to move in the upward direction.

This is known as reaction force.

In short, together these force pairs are known as action-reaction force pairs.

(Forces always occurs in pairs)

This thing shows the presence of Newton’s third law of motion.

### #2 Boy pushing the wall

Do you know how Newton’s third law of motion works, when you push the wall with your hand?

Let’s make this simple.

According to Newton’s 3rd law of motion,

“To every action, there is always an equal and opposite reaction”

When this boy pushes the wall, he exerts some force on the wall. (This is known as action force)

At the same time,

The wall also pushes back the boy, right. (This is known as reaction force)

Now, forces always occur in pairs.

So together these pairs of forces are known as action-reaction force pairs.

And this thing indicates the presence of Newton’s 3rd law of motion.

(Every action has always an equal and opposite reaction)

### #3 Bouncing ball

How Newton’s third law of motion works when you throw the ball on the ground?

According to Newton’s third law of motion,

“To every action, there is always an equal and opposite reaction”

See this,

When this ball is thrown on the ground, this ball applies some force on the ground, right.

This is known as the action force.

At the same time,

The ground also applies the same force on the ball in the upward direction.

This is known as the reaction force.

Therefore, together these pairs of forces are known as action-reaction force pairs.

(As forces always comes in pairs)

Which indicates the presence of Newton’s third law of motion.

### #4 Boy walking in the ground

How Newton’s third law of motion works when this boy is walking?

According to Newton’s third law of motion,

“To every action, there is always an equal and opposite reaction”

When you walk on the ground, you apply some force on the ground, right? (This is known as action force)

At the same time,

Ground also pushes with the same force back on you. (This is known as reaction force)

This thing shows the presence of Newton’s 3rd law of motion.

(Every action has always an equal and opposite reaction)

### #5 Boy swimming in the water

Have you ever wondered how Newton’s third law of motion works while you are swimming in the water?

It’s simple.

See,

According to Newton’s third law of motion,

“To every action, there is always an equal and opposite reaction”

When this boy pushes the water backwards it is known as action force.

At the same time, water also pushes the boy forward, which is the reaction force.

This thing indicates the presence of Newton’s 3rd law of motion.

In short, every action has always an equal and opposite reaction.

### #6 Boy sleeping on the bed

According to Newton’s third law of motion,

“To every action, there is always an equal and opposite reaction”

How Newton’s third law of motion works when you are simply lying on the bed?

Look,

When this boy is lying on the bed, a gravity force is acting on it which is known as the action force.

At the same time,

The bed also pushes the boy upwards, this is known as reaction force.

See this,

Here is the interesting part, (If you have noticed)

When the boy is lying on the bed, gravity pulls the boy downwards, right.

(i.e. boy is applying some force on the bed)

At the same time,

The bed also applies an equal and opposite reaction force on the boy.

(i.e. bed is applying some force on the boy)

In short, here the forces are acting on two different bodies.

As these forces are acting on two different bodies, they are known as action-reaction force pairs.

And this thing indicates the presence of Newton’s third law of motion.

### #7 Boxing

How does Newton’s third law of motion work when you hit someone?

It’s simple, see this.

To every action, there is always an equal and opposite reaction, right.

In short,

When you hit someone, you apply some force with your hand. (This is known as action force)

At the same time,

Your hand also feels some pain, right? (This is known as reaction force)

Which shows the presence of Newton’s third law of motion.

Always remember,

All Newton’s third law examples must satisfy the 3 points which we have discussed earlier.
