yes, because you have to observe your experiment while doing it in case something goes wrong
If you include the effects of falling through air, then you have to know the
shape, size, weight, and surface texture of the objects. You also have to
know the height from which they're dropped, and the temperature, pressure,
and humidity of the air. All these things make a difference in how they fall.
If you ignore the effects of falling through air, like build a giant metal tank
and pump all the air out of it, and ONLY talk about the effects of gravity, then
ALL OBJECTS accelerate at the same rate. If you drop two things from the
same height at the same time, then they both hit the ground at the same time,
traveling at the same speed, no matter what they are. They could be a piece of
tissue and a car !
There are several museums where they have a big glass pipe that you can
see through, and they pump the air out of the pipe and drop a feather and a
bowling ball from the top inside at the same time, and they both reach the
bottom together.
If gravity is the only force on an object, then all objects fall at the same rate.
Because there is no record of all things. As we have partially unknow information, it can never be held as a fact.
Force = 0.20N .F = m ×a .& a = v/t then the f = m×v/t
I believe the correct answer is true. Radial tires generally give the best gas mileage. <span>The advantages of </span>radial tires<span> include longer tread life, better steering characteristics, and less rolling resistance, which increases </span><span>gas mileage. Hope this answers the question.</span>
