# Using Newton's 3rd Law in Tennis to Win

• Navarone666
In summary, the conversation discusses the different situations in which Newton's 3rd law can be used to gain an advantage. Examples include hitting a tennis ball with more force to make it go faster, using a springboard to jump higher, and jumping on a trampoline with a heavy weight to increase the height of the bounce. The relevant equations are listed as Newton's Laws and the conversation concludes with a discussion on releasing the weight at the right time to maximize the effect.

## Homework Statement

In three different situations, clearly describe how you use Newton's 3rd law to your advantage.

N/A

## The Attempt at a Solution

Because of Newton's 3rd law, I know that when I am playing tennis, the harder I hit the tennis ball, the faster it will go towards my opponent, making it easier to score. This is because the tennis ball will have equal magnitude as the action force I exert on it.
(NOTE: My physics teacher read this and told me it was a bad example as it could be used for and example displaying Newton's 2nd law.)

Actually the relevant equations would be Newton's Laws. Could you please list them, and then think of another example of the 3rd Law?

Well, This is like my first year of real physics, so I am guessing a related formula would be:
FNET=ma
And another example I can think of...umm, gimme a bit to think.

Using a springboard to jump over an obstacle, knowing that the magnitude of my action force that I apply on the springboard will be equal to the magnitude of the reaction force it applies on me, I know the harder I push down on the springboard the higher it will launch me, thus takign advantage of Newtons third law.
Hows that?

An advantage i had would involve me standing on a trampoline..where when i jump and land i would be thrown back into the air at a height depending on the force that i had exerted coming down, so if i held a heavy weight which was heavy enough to allow me to jump...when I came down from a jump i would exert more force on the trampoline and I would go higher then before...

I think that would be a valid answer but i may be wrong...

In my opinion, to take advantage to that you would have to release the weight just as you are bouncing back up, because then you would have the magnitude of the weight and your body mass acting on just you and not the weight, giving you extra height. In my opinion.

## 1. How does Newton's 3rd Law apply to tennis?

In tennis, Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This means that when a player hits a ball with their racquet, the ball exerts an equal force back on the racquet. This is what allows the ball to be propelled over the net.

## 2. How can I use Newton's 3rd Law to improve my tennis game?

By understanding and applying Newton's 3rd Law, you can improve the power and accuracy of your shots. For example, by using a combination of your own force and the force of the ball, you can generate more power and control in your shots.

## 3. Does the weight of the tennis racquet affect the application of Newton's 3rd Law?

Yes, the weight and design of a tennis racquet can affect how effectively you can use Newton's 3rd Law to your advantage. A heavier racquet may allow you to generate more force, while a lighter racquet may allow for quicker swings and better control.

## 4. Are there any other laws of physics that can be applied in tennis?

Yes, there are many other laws of physics that can be applied in tennis, such as the law of inertia, the law of acceleration, and the law of momentum. These laws can help you understand and improve upon different aspects of your tennis game.

## 5. Can Newton's 3rd Law be used in doubles tennis?

Yes, Newton's 3rd Law applies to all types of tennis, including doubles. In fact, understanding and utilizing Newton's 3rd Law can be especially beneficial in doubles, as it can help you coordinate and communicate with your partner to create more powerful and strategic shots.
