The speed will not be constant. If air resistance is not significant, the speed of an object will increase about 9.8 meters per second every second. This is often expressed as an acceleration of 9.8 meters per square second.
The force is called the weight. In everyday usage mass and weight are loosely given the same units (say, grams) but scientifically the gravitational force on a mass m is actually mg (dynes) where g is the acceleration due to gravity. The Newton's law "force = mass x acceleration" means that if you drop it, the acceleration "a" is given by mg = m x a so that a=g and it falls with acceleration "g"
On or near the Earth, gravity accelerates every falling object at the rate of
9.8 meters per second (32.2 feet per second) every second. That means its
speed keeps increasing at that rate.
Acceleration due to gravity is 9.80665 m/s², commonly used as 9.81.
yes
Because gravity pulls the masses down at the same rate.
The acceleration due to gravity alone on Earth is about 9.81 meters per second-squared.

No GaleleoAdditional answerNobody discovered gravity. Everyone in the world has always been under the influence of gravity, but never thought about it. Newton was the first person to do so.And Galileo did not discover gravity. What he did was to show that two objects of different weights would accelerate under gravity at the same rate. He dropped two objects from the Leaning Tower of Pisa to prove it.
Yes. All objects fall at the same rate, but the rate varies depending on the force of gravity.
It does. Earth, along with everything on it is pulled toward the sun by gravity. However since they are all pulled in the same direction at the same rate, everything stays on Earth.
Gravity pulls everything down at a rate of 9.8 m/s2 .
Because gravity pulls the masses down at the same rate.
True
The rate is 9.8m/sec
Gravity causes all objects to accelerate at the same rate in a vacuum. In air there is air resistance which can slow some objects down eg a parachute. So, yes, in a vacuum all objects reach the same speed in the same time period.
