Question

does anyone know what V1=V0+GT is for? also what's G and T?

Answer 1

this is the most basic equation for motion at constant acceleration, commonly seen as \(\Large v_1 = v_0 + at\)

t is time, a is acceleration -- in your equation it is entered as g representing acceleration due to gravity

\(v_1, v_0\) are final and initial velocities....

Answer 2

thanks! i have another question:

when an item is dropped is the initial velocity always 0?

Answer 3

depends!!

if it is dropped out of something else that is moving, that might not be true. eg a typical example is something dropped from a rising hot air balloon. the thing will have an initial upward velocity as it is also rising with the balloon when it is released.

but ordinarily, yes, if you are standing still and just drop something out of your hand, it will have zero initial velocity.
