==== Not really. True that gravity affects all objects equally, but unless we're in a complete vacuum, we have to take into consideration wind resistance in the form of the ratio... surface area/mass. Which ever has the greatest surface area to mass ratio will fall slower than the one that has a lesser surface area to mass ratio. Take for instance, an ordinary plastic shopping bag. If you ball it up as tight as you can, you reduce the exposed surface area while keeping it's mass unchanged. If you drop it, it will fall to the ground quickly. If you open it up and flap it around and then drop it, it will float to the ground slowly. ====
The penny will hit the ground first. However, if there was no atmopsphere then they would both hit the ground at the same time.

Well, after the plastic bags get thrown away on the ground, they go into the ocean and kill a lot of animals. :(
The ball is a projectile, and as such, the only force acting on it after it has been thrown or kicked is gravity, so after it reaches its highest point, it will begin to fall to the ground at the rate of 9.8m/s2 .
The football has (gravitational) potential energy because of its position above the ground. It also has kinetic energy because it is moving. The combined energy is called mechanical energy.
If it's in a field it's probably because the field has dry grass and that causes fires to start. If it's not in a field then someone might have thrown a cigarette on the ground. That has happened a lot.
It falls and splats on the ground! DA Genius!
It could reach up to 100 mph, with a regular penny.
Male Empire.
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!

Many of the rutals were thrown out during the Gupta empire.
It depends on the height of the building and also on the direction the object is thrown in (up, down etc.).
Gravity is the force which makes a thrown ball fall back to the ground. It is the force which attracts all objects to the Earth.
a stone is thrown from the top of a building with an initial horizontal velocity of 20 m/s if it is thrown from a height of 30 m and air resistance is neglected, find: a) time it takes the stone to reach the ground b) range
