If two objects of the same mass are dropped from different heights will they reach the ground at the same time
They won't touch the ground at the same timejbriggs444 said:What do you think?
Can you elaborate on your reasoning -- does one or the other have a greater acceleration?ilori said:They won't touch the ground at the same time
The object at greater height will have a greater velocity but since it has a greater distance to cover it will take more time to touch the ground.jbriggs444 said:Can you elaborate on your reasoning -- does one or the other have a greater acceleration?
*SMACK HEAD*. You said different heights rather than the classic different masses.ilori said:The object at greater height will have a greater velocity but since it has a greater distance to cover it will take more time to touch the ground.
yes, that's correctjbriggs444 said:*SMACK HEAD*. You said different heights rather than the classic different masses.
Yes, you are right. The higher one takes longer to fall.
The acceleration is the same (assuming that the starting heights are not significant compared to the Earth radius) and constant for both. This means that at any given time (ignoring air resistance) both objects are going at the same speed, so that the object starting higher can never catch up.jbriggs444 said:Can you elaborate on your reasoning -- does one or the other have a greater acceleration?
The concept behind "Same Mass Objects Dropped: Same Time" is that objects with the same mass will fall to the ground at the same rate when dropped from the same height, regardless of their shape or composition.
This is possible because the acceleration due to gravity is constant for all objects. The mass of an object does not affect the rate at which it falls, only the force of gravity does.
No, air resistance does not play a role in this concept. In order for objects to fall at the same rate, they must be in a vacuum or an environment with minimal air resistance.
Galileo Galilei famously conducted experiments using different objects of varying masses and shapes from the Leaning Tower of Pisa to show that they all fell to the ground at the same rate. This concept has also been proven through various other experiments and demonstrations in a controlled environment.
In the real world, there may be some slight variations in the rate at which objects fall due to factors such as air resistance, but in a controlled environment with minimal air resistance, the concept holds true. Additionally, objects with extreme differences in mass, such as a feather and a bowling ball, may not fall at the exact same rate due to air resistance and other external factors.
