## Newton's Third Law

Newton's Third Law, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This fundamental principle of physics is applicable in many areas of our daily lives, from the way we walk to the way a rocket propels itself into space.

To calculate the force of an action and reaction using Newton's Third Law, **we use the formula:** F=ma, where F is the force, m is the mass of the object, and a is the acceleration. The acceleration can be calculated by using the formula: a=\dfrac{V-V_0}{t} where V is the final velocity, V₀ is the initial velocity, and t is the time.

An example of Newton's Third Law in action can be observed in the propulsion of a rocket. As the rocket expels fuel out of the back of the nozzle, the fuel exerts a force on the rocket in the opposite direction, propelling it forward. By calculating the force of the expelled fuel and the mass of the rocket, we can determine the acceleration of the rocket and ultimately, its velocity and trajectory.

In addition to understanding the motion of objects, Newton's Third Law also helps us to understand the forces acting on structures and machines. Engineers use this law to calculate the forces on bridges, buildings, and other structures to ensure they can withstand the loads placed on them.

In conclusion, Newton's Third Law, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This fundamental principle of physics is applicable in many areas of our daily lives, from the way we walk to the way a rocket propels itself into space.
