    hi, can i ask. is there a mistake that 14.33 video the equation of the free fall motion,isn;t v^2=2as---0^2=20^2(-9.81)s?

      Ya, I think so too. u^2 should be 400 instead of 20

    if I throw a ball with zero gravity and no air resistance to the sun, will the ball reach the sun?

      Nope, the ball will eventually melted due to heat of sun

      Hi there! Technically, yes. Assuming that you are throwing the object from Earth, and gravity and air resistant are non-existent in all realms, the ball you threw would keep moving at the speed and direction that you threw it in. There wouldn't be any gravitational force or external factor (air resistance) holding the ball. Thus, there is a possibility for it to reach the Sun. Although there are many other things that will happen if there's no gravity so maybe the ball reaching the sun wouldn't even be the biggest problem
