v_terminal = (Sqrt(2mg)/(C*p_air*A))

The purpose of the investigation was to see how terminal velocity acts on objects with different weight.

Hello, I am finishing my IB internal assessment in physics. I have thrown four balls (with different masses, 400,450,475,500 grams) from a height, which is approximately 23 meters. My teacher told me to set up a graph which showed mass vs. vt^2. He said that the inverse of M=...

I've decided to drop the ball from a tall building and use the camera to determine the change of velocity. My calculations will look like this: ∑F = ma F_f=mg=0 C×Vt2=mg vt= √mg/c c=(0.5) CD×ρ×A I would test my numbers by calculating the distance of travel (ball). Then, I would try to...

Thanks for the help everyone! I will try to shoot the ball high up in the air and use a camera to analyze the speed.

Sorry about the unspecific details, I meant terminal velocity. I wrote this just after having a class about thermal energy. Terminal velocity is when drag force is the same as force of gravity. This will then push the ball downwards, when the object is in mid-air. I would need to hit the ball so...

Hello, I am an IB HL Physics student. I am thinking of doing my IA on the thermal velocity of a soccer ball. I will be using a soccer ball shooter (machine) to simulate the thermal velocity. I have a couple of questions: what is the thermal velocity equation, which would fit for a soccer...
