Does the air pressure change when a tennis ball is hit into the air?

When a tennis ball is hit into the air, the air pressure around the ball changes. The air pressure is higher in front of the ball than behind it. This is because the ball is moving through the air and pushing the air out of the way. The air in front of the ball is compressed, which increases the air pressure. The air behind the ball is less compressed, which decreases the air pressure.

The difference in air pressure between the front and back of the ball creates a force that pushes the ball forward. This force is called drag. Drag is a type of friction that slows down the ball. The faster the ball is moving, the greater the drag force.

The air pressure also changes as the ball falls back to the ground. The air pressure is lower in front of the ball than behind it. This is because the ball is moving through the air and creating a vacuum behind it. The air in front of the ball is less compressed, which decreases the air pressure. The air behind the ball is more compressed, which increases the air pressure.

The difference in air pressure between the front and back of the ball creates a force that pushes the ball backward. This force is called lift. Lift is a type of force that helps the ball to stay in the air. The faster the ball is moving, the greater the lift force.
