Does a frozen or regular tennis ball fall faster?

the only way they could fall at different rates is if one were smoother than the other. temperature has little effect on the weight of a solid object.


What is the difference between free fall and terminal velocity?

The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity. .


A 10 pound weight and a 2 pound weight are dropped from the same height at the same time Which weight will hit the ground first?

Why do you ask. Do you think they should not hit the ground at the same time. Do you think perhaps a heavier object should fall faster. Let's check it out. Take a 10-pound stone and a 2-pound stone. We're pretty sure that the 10-pounder is going to fall faster than the 2-pounder does, but let's try it out anyway. Take both of your stones to the top of the leaning tower, but don't drop them yet. Before you drop anything, tie your stones to the ends of a 6-foot string, then drop them together. The 10-pounder wants to fall faster, so it hurries the 2-pounder ahead a little. The 2-pounder wants to fall slower, so it holds the 10-pounder back a little. Together they fall a little faster than the 2-pounder wants to, but a little slower than the 10-pounder wants to. Right ? So when they fall together, they fall slower than a single 12-pound stone would fall. Some people would be perfectly OK with that. We've known for roughly the past 500 years that every object on earth falls with the same speed and acceleration and hits the ground at the same time, unless air holds it back. If you pump the air out of a tall tube and then drop things inside the tube, a bowling ball and a feather drop together and hit bottom at the same time.


On the first day of spring and fall the sun is located over the?

For spring the tropic of Cancer, for fall the tropic of Capricorn (i think, because I'm pretty sure that summer it's over the equator, but I'm a little fuzzy as to where it is in the winter. but I'm still pretty sure the equinox's are over the tropics.)


How does knowledge of seasons help farmers?

Knowledge of seasons helps a farmer because as seasons change, heat and humidity changes. Crops also change with the seasons, and if the crops are not harvested before the season ends, then they will most likely lose the crop. Seasons come with new weather, and around my area it's Spring comes with tornadoes (heat and cold clash) and moistness, Summer comes with dry heat, Fall is cold and moist, and Winter is fairly dry and freezing.
