two balls with different masses but identical shapes and sizes are droped from a certain height. Which one would land first if there is no air resistance?

Gravity works uniformly on all objects. Two objects dropped from the same height with no air resistance would strike the ground at the exact same time because gravity is a constant force and does not depend on the object's mass. The same is seen in pendulums. If you and I swing on a swing set beside one another and you swing higher than I, we will take the same amount of time to complete a full swing regardless of our mass. Try it out!

if they are identical they will hit the ground together with or without air resistance
its the shape that matters not the mass
in no air resistance enviroment every object will hit the ground in a certain time even if the balls are not identical

OK... It's easy.... according to the relation: S=vt+ 1/2gt2 (the last 2 means to the power of two) if height S is the same, initial velocity v is the same and acceleration due to gravity g is the same for both balls, then time taken to reach the ground t is the same. THE PROBLEM DOESN'T DEPEND ON MASS, SHAPE OR VOLUME!! Good Luck......

They will reach the ground at the same time, if the buoyancy of air (not resistance) is not an issue. Foe example, a rock and a wood, a steel ball, a copper ball... all of them will reach at the same time.
This is what Galileo proved by his experiments from the leaning tower of Pisa.

If there is no air resistance, any two objects will fall at the same rate.

They would land at the same time as the accelaration of gravity would be the same. Even if we drop a bowling ball and ping pong ball at the same time. It would land at the same time.
I hope this helps. :)

Unless these balls was as big as the moon, they would land at the same time.
