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.
Forget about "down". That's just the name we give to the direction that points toward the earth. "Down" in New York and "down" in India are opposite directions. What gravity does is attract every...
You're describing a behavior that Galileo proved false 500 years ago. Gravity does not pull heavier things down faster. If you can eliminate the effects of air resistance, then anything you drop from...
Objects have a mass which gives them a gravitational force. All objects have a graviational force field which pulls on other objects. The earth's gravitational force holds us down. It also pulls on...
