# What forces act on a tennis ball?

Forces on a Tennis Ball

• Thrust – momentum of the racquet pushing the ball forward.
• Gravity – the weight of the ball acts downward from the ball’s center of gravity.
• Drag – refers to the force, in this case – air resistance, acting in the opposite direction (flight direction) of the movement of an object.

## Thereof, how is Newton’s second law used in tennis?

Second Law

During your serve, the mass of the tennis ball remains constant. Therefore, you can see in this equation that the more force you apply to the constant mass of the tennis ball on the serve, the greater the acceleration of that serve will be until it reaches its top speed.

In this regard, is hitting a tennis ball with a racket mechanical energy? When the ball hits the racquet, it gets squished, and it gains elastic energy, since it is compressed. Naturally, since there is pressure inside the ball, it will want to regain its original form, and when this happens, the elastic energy is turned back into kinetic energy.

## Additionally, how fast does a tennis ball go after being hit?

When a tennis player serves a tennis ball, the serve can reach speeds over 124 mph (200 km/h). But what’s happening to the ball when it gets hit? This 142 mph (228.5 km/h) serve in slow motion (6,000fps) shows us. Tennis balls are hollow, pressurized, and made of rubber that’s covered in “optic yellow” felt.

## What are 3 facts about tennis?

Tennis Fun Facts

• Before tennis players used rackets, people would use the palm of their hands to hit the ball back and forth over the net. …
• Before yellow tennis balls, they were white. …
• The origin of the tennis term “love” is unknown. …
• During a match, a player on average runs 3 miles. …
• Racket versus racquet.

## Why does a tennis ball not slow down very quickly when hit?

Why does a tennis ball not slow down very quickly when hit? The under-inflated ball encounters somewhat less air resistance (air drag). It would therefore not slow down as quickly and would be able to travel further.

## What is the weight of tennis ball?

The International Tennis Federation (ITF) oversees the official ball, but the accepted range of size and weight allow for variances from ball to ball. Tennis balls must measure from 2.57 to 2.70 inches in diameter and weigh between 1.975 and 2.095 ounces, leaving a bit of wiggle room for differences.

## When a tennis ball hits a tennis racquet what causes the ball to change directions?

Experiments show that the friction force on the bottom of the ball drops to zero and reverses direction during the grip phase. As a result, the ball distorts in the tangential direction and in the direction perpendicular to the surface. When the friction force reverses, it actually pushes the ball forward.

## Why is acceleration important in tennis?

The slower the movement speed, the more the foot will be in contact with the ground and the more force is needed to generate an efficient, explosive action. Which is why acceleration drills are critical. During speed & acceleration workouts, players must ensure to take a full (or near-full) recovery between sprints.

## Does force affect acceleration?

A net force on an object changes its motion – the greater the net force, the greater the acceleration. More massive objects require bigger net forces to accelerate the same amount as less massive objects.
