The gravitational pull of earth makes it so that a falling object will fall at 9.81meters/second, and accelerate at that speed. So if an object falls for 2 seconds, its going 19.62m/s. Also, if you throw a ball straight up into the air from ground level (we are currently ignoring air and wind resistance) Then when it gets to the peak of the arch, it will be moving at 0m/s vertically. This means that when the ball gets back to the exact elevation that you threw it from, gravity will have sped it back up to the EXACT same speed that it had when you released from your hand, only now its going the other way.
The rate of acceleration is constant.
The acceleration of falling objects in Earth is about 9.8 m/s2.
Ask around to find out what planet they're falling on.If it's the earth, then the acceleration is 9.8 meters (32.2 feet) per second2.
All objects irrespective of their masses in a vacuum where there is no air resistance will fall at an acceleration of 9.81 m/s²
