Why do two objects of different mass and dropped from the same height hit the ground at the same time?

If air resistance can be ignored, then both objects are moving under the same force: gravity. The force is directly proportional to the masses of the objects.
Thus if the masses are Mp and Mq
then Gp = k*Mp and Gq = k*Mq where Gp and Gq are the forces acting on the two bodies.
The acceleration of the two objects is inversely proportional to their masses. [F = m*a => a = F/M]
So acc(p) = Gp/Mp = (k*Mp)/Mp = k
and acc(q) = Gq/Mq = (k*Mq)/Mq = k
That is, the acceleration of the two bodies is the same. Consequently, because they start from rest from the same height, they will hit the ground at the same time.

∙ 7y agoThis assumes that air resistance can be neglected.The reason is that both are accelerated at the same rate by Earth's gravitational field - about 9.8 meters per second squared.
Consider that an object that has (for example) 10 times more mass, and will therefore be attracted 10 times as strongly by Earth, also has 10 times as much inertia.

Why do 2 objects of different masses dropped from the same height hit the ground at the same time?
Most likely because they're the same weight. Objects can have completely different masses and have the same weight.
Why dropped objects hit the ground at the same time?
Dropped objects hit the ground at the same time (as long as they're dropped from the same height) because the acceleration of gravity is constant. On earth, it's 9.8 meters per second (32.2 feet per second) every second.
What three very different sizes and weights are dropped off a tower on the moon Which factor of the objects will determine which hits the ground first?
Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
If two object of different density are dropped simultaneously which one will hit the ground first?
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
Why does 3 spherical object with different mass will hit the ground at the same time when dropped simultaneously from the same height?
Gravity.
What will hit the ground first a pencil or penny?
There are many factors that can affect the time for these objects to drop. The height at which each object is dropped is a factor since the height is proportional to time. if the height at which these objects are dropped are the same, then the time for them to drop to the floor is the same. Since the acceleration due to gravity at sea level is 9.81 m/s^2 for all objects no matter the mass, both objects will accelerate at the same rate which means they will reach the floor at the same rate. All in all, both the pencil and the penny will hit the ground at the same time.
True or false. A 100 lb object and a 2 lb object are dropped from the same height The 100lb object will hit the ground first?
If both objects have similar air resistance factors, they will both hit the ground together.
How long will it take an object dropped from a height of 500 feet to hit the ground?
4 seconds
Would a bowling ball and a penny hit the ground at the same time if dropped from an equal height?
Yes
A ball was dropped on a top of the building and hits the ground after 15 s. What is the height of the building?
381 metres
How long does it it take an object of 4 kg to hit the ground considering another object with a mass of 2 kg took 3 seconds to hit the ground?
Assuming they were in a vacuum, if both objects were dropped from th esame height, then both take the same length of time to reach the ground. All masses fall with the same acceleration, reach the same speed in the same period of time, and hit the ground at the same time. Otherwise and if there is an atmosphere or if they are dropped from different heights, you have not presented information; shape and size are the most important factors.
A tennis ball is dropped from 1.55 m above the ground It rebounds to a height of 0.824 mWith what velocity does it hit the ground?
31 m/s
