Does gymnastics deal with gravity?
Yes. Gymnasts learn gravity way before they learn it in school!! We have to learn that when doing a flip you have to set (shoot up in a strait body really fast) before flipping so the gravity doesn't pull you down before the flip is done!
Do all bullets drop the same vertical distance in equal time?
Bullets will drop almost the same vertical distance in equal time. The limitation is the vertical drag force on the bullet. If fired in a flat trajectory, a bullet will start with no vertical velocity. As it continues on its path however, the force of gravity will impart some vertical velocity to it. Initially the vertical component of the drag force will be negligible, but the longer it flies, the faster it drops. At some point the drag force becomes noticeable and the roughness of the bullet surface and geometry of the bullet begin to play a role in how much vertical drag force is exhibited. Most of the time a bullet will hit its target before this effect makes much difference, but if you fired two different bullets from the top of a very high mountain and tracked their flight you would probably find them dropping at different speeds towards the end of their flight.
Is the vertical motion of a projectile dependent on its horizontal motion?
They fall at the same rate. So if you aim at an object before it falls from a height and shoot just as it is released then the projectile will hit the falling object. This happens because gravity is always the same (at small heights) and has the same effect on the object with no horizontal displacement as it does on the projectile with horizontal displacement.

Till there is no gravity!! Jess
Why displacement is called vector?
well i guess because there are multiple ways to make a distance...let say A to B. it can go round and round before it finally reach B. You can go either direction to reach B. but when it comes to displacement, it demand the shortest distance to reach B, which is only one way to do it, i think this qualify displacement to have a specific direction.
How did NASA know that the Moon's gravity was less than that on the earth before they got there?
NASA knew the mass of the Moon before going and could calculate the pull of gravity relative to the earth. Weight is just the measurement of the strength of gravity while mass is how much material is packed into any one object. Gravity increases as the mass of an object increases so the Moon being much smaller than the earth would therefore have less gravity.
Why does the ball stop when it is thrown before it goes down?
It doesn't change its velocity suddenly. The change is gradual.Any object that is in the air is accelerated by gravity towards the earth.The value of acceleration g is about 9.8 m/sec2. Therefore,The vertical speed of a ball thrown at vertical velocity v0 will be v0-gt.When t=v0/g, the vertical velocity becomes zero, so the ball starts to fall down.
Was gravity discovered before antibiotics?
The laws of gravity as expressed by Sir Issac Newton were determined before Dr. Louis Pasteur discovered penicillin.
Why is your weight regulated by earth's surface gravity instead of Jupiter's since Jupiter has such a great surface gravity and the planet is so big?
Yes, Jupiter has stronger gravity at its surface than does earth. However, to understand why we are affected by earth's gravity instead of Jupiter's you must go to Newton's laws. Jupiter's gravity decreases according to the distance. You will need to look at the formula. Then you can calculate a number with a decimal place and a bunch of zeroes before you reach the first significant figure. You can then figure out how much Jupiter's gravity affects you over this distance. Go ahead. Find the formula. Get the answer.

Had anyone heard of gravity before newton introduced it?
Gravity was discovered long before Newton was around. Newton just postulated gravities relationships with acceleration and mass.
Why do you measure the mass of an object before measuring its volume using the displacement method?
To get the accurate weight/mass before the objects gets wet.
How do you calculate a persons volume in cubic meters?
Place them in a known volume of liquid, then measure how much the liquid rises. That's the way to do it, but remember the water displacement will be altered whether you inhale, or exhale before you imerse yourself, but hey who cares. This method is called Archmedies principal.
How is the ABV on a bottle of wine calculated?
Using a hydrometer, the specific gravity (SG) of the wine is measured before and after fermentation. The numbers are then used in the following formula to calculate Alcohol By Volume. ABV = (initial SG - final SG) / 7.36
Which scientist determined the nature of the force that keep the planets in their orbit?
Isaac newton with his theory of gravity is probably the answer. But even he couldn't really explain the "nature" of gravity.Isaac newton discovered the nature of gravity when he described how to calculate the force from the two masses and their distance. Before that the concepts of force and mass had to be defined, and Galilelo played an important part in that.
