how long does a ball touch the ground when it bounces

The softer the strings, the faster and higher the ball bounces. The surface does not spring back fast enough or efficiently enough to aid the ball in its bounce, so that energy is “lost.” (This is the opposite of what happens on strings. If the court is soft, energy will be lost deforming the court surface. The harder the court, the higher the ball will bounce. The magnitude of the upward force, known as the “ground reaction force,” is determined by the vertical incident speed of the ball and the relative hardness of the court and the ball. These two forces have far-reaching consequences, with effects that may seem contrary to intuition and experience. When a ball hits the court, a vertical force pushes the ball up and a horizontal force acts to slow the ball and change its spin. And these in turn dictate what kind of strokes and strategy a player adopts as he or she learns the game.

During that five one-thousandths of a second, the ball’s speed, spin, direction, height, and angle are changed. That five-millisecond bounce dictates everything, including shot selection, tactics, strategy, stroke mechanics, grips, and training. And for good reason - the bounce of the ball is completely different on each surface, and it is the bounce that determines the game. The events, flow, and look of the game are completely different. Watching tennis played on the red clay of Roland Garros at the French Open and on the Centre Court grass at Wimbledon can seem like watching two different sports. Understanding how the ball bounces can help you and your students pick and read shots. In this case, it should be touched on the ground, using both hands.Home » TI magazine » Science » Follow the Bouncing Ball Follow the Bouncing Ball On wet days, the ball will skid away or fail to bounce back.

Running in straight lines, and extend to weaving and dodging.īeing able to bounce the ball with both hands will enable you to guide the ball down better and kick with either foot.Standing and bouncing, and then extend to walking and bouncing.Bend over and bounce the ball standing still.The distance at which the ball is thrown out in front is directly related to the player’s speed – the faster they are running, the further out in front it must be thrown. The ball is bounced far enough in front so that it will bounce into the player’s hands as they run forward.

The ball strikes the ground at an angle of about 45 degrees.

The ball is held slightly on top by the bouncing hand.

A player in possession can run as far as they like, as long as they bounce the ball every 15 metres. One of the great features of Aussie Rules is its free-wheeling nature.
