thanks i just got home so will spend next few hours getting it to work better thanks -

possibly is it air resistance that slows a ball down when traveling upwards? -

Undergrad Trying to understand the bouncing ball
ok so this is where I am at... What is the velocity after the bounce? Use the COR: vi=(COR)(vf)So this is the initial velocity of the second bounce. How high does it get? Again use the conservation of energy, but the other way around: 12mv2=mgh⟹h0=v2i/2gThis is how high up the second bounce... -

oh ye forgot to mention my axis is inverted but i understand what you meant :) the ball now bounces up and gets a lower bounce height until it comes to a stop but its speed of how it moves is always the same... how do you make it go slower on the bounce back up? -

ahh I am confused... ok so let me change it around velocity = force + gravity * (Mathf.Pow(Time.time,2)) so when ball is in air to start it has no force only gravity... when it hits the floor i get the velocity downVelocity = Mathf.Sqrt((2 * (9.8 * startingHeight))) then i work out the new... -

so say I am imitating a tennis ball the COR is roughly 0.75 (going on what someone wrote in other thread) i think my problem maybe i apply gravity in beginning but never add a force(if any) so when it hits the floor how does the new velocity alter the speed in which it bounces back up? -

Undergrad Trying to understand the bouncing ball
hi all, ok i read another post from this forum about the bouncing ball but i didnt want to start asking questions when i never made the thread ok so I am programming a program that starts with a ball in the air and it will automatically start to fall here is a simplified look at my code to...
