If a tennis ball is cooler then the atoms have less energy so it may hypothetically bounce lower than if it was warmer
Very little
the hotter the tennis ball is the higher it will bounce because the molecules are moving faster and the pressure is decreasing. Opposite when it is cold.
When struck by a tennis racket the factor which effects the ball is how much spin is applied to the ball (more specific top spin) and the surface which you play on. For example: hard courts will bounce alot higher then grass courts.
The temperature of a tennis ball can affect its bounce height. As temperature increases, the air molecules inside the ball expand, causing it to bounce higher. Conversely, at lower temperatures, the ball may not bounce as high due to decreased air pressure.
No Minimum Height! :)
3.5ft or 4ft
The official height of a table tennis net is 15.25 cm(6.0 in). Which converts to 0.1525 metre.
5'4"
The height of the net is 1 m height and the height of the racquets may vary according to the model you buy.
A table tennis table is 2 feet 6 inches (76cm) high.
Table tennis rackets can be any size according to the rules.
exactly 3 feet short
