Not 100% sure but i think it was Galileo of Newton
no, some are heavier therefore fall faster. not! all objects fall at the same rate no matter what size, Galileo said that DUH! both are wrong... partially. Some objects have more air resistance than others. The more air resistance, the slower an object will fall to the ground. ;-) -Th
No, most objects do not travel at a constant speed. Factors such as forces acting upon the object, changes in direction, and external factors can cause objects to speed up, slow down, or change direction. Objects can also have variable speeds due to changes in energy or motion.
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
The study of speed is called kinetics. It involves analyzing the motion of objects and the factors that affect their speed.
Falling objects are accelerated by gravity, while objects moving upward are being decelerated by gravity. Gravity pulls objects downward, increasing their speed, while it opposes the motion of objects moving upward, decreasing their speed.
it was MAxwell the dude who discovered electromagnetic waves
The evidence for the existence of dark matter in the universe includes the extra mass of Galactic clusters discovered by Fritz Zwicky, and the spinning galaxies which rotate at the same speed as discovered by Vera Rubin.
By a process called blink comparator. By observing the same area of sky it is possible to see what objects are moving and at what speed.
The second species in any environment.It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
when you know both speed and direction of an objects motion you know the velocity of an object.
The speed varies according to the refractive index of the objects.
Speed only tells how fast something is going, while velocity tells speed and direction.
not sure

Different objects can have different speeds; also, the same object can have one speed now, and a different speed later.
First of all, it is scientifically impossible for any type of matter to reach light speed. Secondly, if said matter is near light speed, then that matter will increase in density as it increases in speed. Also, time will slow down around the matter as it increases in speed.
That speed is not constant. The longer an object falls, the faster it moves.For each second an object falls, its speed increases by 9.8 meters (32.2 feet) per second.You're correct in suggesting that all objects fall with this same "acceleration" with no air resistance,no matter what their shape, size, or weight might be.
