Because the hard surface doesn't absorb any of the energy of the tennis ball - thus the ball bounces higher than if it was dropped on a softer surface.
A softer ground, such as clay, will decrease the bounce of a tennis ball, a harder ground, such as concrete, will make the ball bounce higher.
Test is!. A tennis ball is going to bounce higher.
friction
Rough surfaces cause much more friction than smooth surfaces which drag the ball down alittle then what smooth surfaces do.
It really depends how hard you bounce either one, but i think the tennis ball.
it will bounce higher if its hot
because the hard court is harder so it can have more energy bounce off than soft grass
The tennis ball will bounce higher in hot weather than in cold weather.
Tennis balls.
Given the same ball manufacturer and product, warm tennis balls will bounce higher than cold ones. However, there are specially made tennis balls that will bounce equally high for a given environment, whether it be in low or high altitudes, temperatures, humidity, court surfaces, etc.
Due to the fact that a tennis ball is traveling at a higher speed when dropped from a higher height, it will rebound with greater speed and bounce higher.
A tennis ball does bounce higher!!!:]] x
