## What is the motion of the tennis ball?

Rotational motion plays a huge role in the game of tennis. The rotational motion, or spin, of a tennis ball affects its trajectory through the air, as well as how it bounces. Players make constant use ball spin to affect their shots and make them more difficult to return.

## What type of motion does a tennis ball have in the air?

Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. The object is called a projectile, and its path is called its trajectory.

## What are the forces acting 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.

## What is projectile motion in tennis?

The principle of projectile motion influences the displacement of the ball from the moment it leaves the racquet to the instant it lands on the service area. The location of where the ball will land is influenced by the ball location at time of impact and the velocity immediately after the connection.

## What are tennis moves called?

Thus tennis shots can be categorized according to when they are hit (serve, groundstroke, volley, half volley), how they are hit (smash, forehand, backhand, flat, side spin, block, slice, topspin shot), or where they are hit (lob, passing shot, dropshot, cross-court shot, down-the-line shot).

## What are the motions of a ball?

The motion of a ball is generally described by projectile motion (which can be affected by gravity, drag, the Magnus effect, and buoyancy), while its impact is usually characterized through the coefficient of restitution (which can be affected by the nature of the ball, the nature of the impacting surface, the impact …

## What happens to the tennis ball’s motion?

Once the ball is struck it flies over the net before being pulled down towards the ground by gravitational pull. If it weren’t for gravity’s existence, the tennis ball would continue to fly in a straight line forever. Newton’s second law suggests that force is equal to mass times acceleration.

## Does a moving tennis ball have energy?

As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface. When the ball collides, the kinetic energy is transformed into other forms of energy.

## What are three physical properties of a tennis ball?

• Mass: 56-59.4 gm.
• Size: 2.575-2.700 inches (6.541-6.858 cm)
• Bounce: 53-58 inches (135-147 cm)
• Forward deformation: 0.220-0.290 inches (0.559-0.737 cm)
• Return deformation: 0.315-0.425 inches (0.800-1.080 cm)

## What is the third law of motion in tennis?

The ball exerts an equal and opposite force on the racket. This is the reaction force. Newton’s third law explains how many sports injuries are caused. The more force you use to a hit a tennis ball, the more reaction force your arm receives from the racket.

## What is the symbol for tension?

A string or rope exerts a contact force on an object when it pulls on it. We call this a tension force, represented by the symbol T. Tension is always directed along the line of the rope or string, with no component perpendicular to it.

## What is an example of a horizontal motion?

• A boat travelling in a river.
• A bullet fired from a gun.
• Throwing a ball or a cannonball.
• Movement of a billiard ball on the billiard table.
• The motion of the planet Earth around the Sun.

## What is the horizontal and vertical motion of a projectile?

In a Projectile Motion, there are two simultaneous independent rectilinear motions: Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle. Along the y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.

## What is the velocity of a tennis ball?

Between 122 feet per second( 83.2 mph ) at air temperature of 20C and 123 feet per second ( 83.8 mph ) at 0C. That’s assuming that the ball is hit perpendicular to the baseline, the net is 3.5 feet high, no spin on the tennis ball and no cross wind.
