Get PriceModern tennis balls must conform to certain criteria for size, weight, deformation, and bounce criteria to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 6.54–6.86 cm (2.57–2.70 inches). Balls must have masses in the range 56.0–59.4 g (1.98–2.10 ounces). Yellow and white are the only colors approved by the ITF, and most balls ...

Get PriceEnergy can be stored in an object by lifting the object to a certain height. This energy is called gravitational potential energy. The gravitational potential energy of an object depends on how heavy the object is and how high it is. ... Do not drop the balls from an excessive height over 1 meter.

Get PriceProjectile motion is a form of motion experienced by an object or particle (a projectile) that is projected near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible). This curved path was shown by Galileo to be a parabola, but may also be a line in the special case when it is thrown ...
