Is acceleration affected if we throw an object down instead of dropping it down?

Question

If an object is free-fall then the initial velocity is 0m/s and the acceleration is 9.8 m/s^2 in magnitude, but i need help figuring out how acceleration is affected when we throw it down. Please, help.

Answer 1

acceleration will not be affected....
the initial velocity will be though.

it's acceleration is only affected while it is still in ours hand.. once we let go, we are no longer accelerating that object. gravity takes over.
we've only given it a velocity

Answer 2

Honey, unless definitions have changed over the course of the past 40 years, if an object is in free fall, it has velocity, even if it is synchronous orbit. If it did not have a velocity then it would acquire some because of the affects of gravity. Acceleration is the the result of energy expended to get an object moving, or to increase it's speed. When you press down on the gas pedal of your car, you cause the engine speed to increase and cause the vehicle to begin moving, that is acceleration. The initial impulse from throwing the object down, if that is done at an angle perpendicular to the direction of flight of you and your object then it's forward velocity will not change, but the lateral acceleration will naturally increase, and the velocity obtained from the action will continue until something slows it down, such as gravity drag, or it hits something.

Answer 3

No, but your ending velocity would be. I would do the calculation as if the object started from standing still and simply add the initial downward velocity (how fast you thruw it downward) to the ending velocity. Remember that when the object began free fall, its velocity may not have been zero, but its force of accelleration was. Since acceleration is a function of time, no acceleration accrues until time passes.

Answer 4

acceleration isn't affected at all. you just start with a greater initial velocity, so the object will reach the ground quicker but the acceleration is constant at 9.8 m/sec^2

Answer 5

Mike got it pretty much right. While in your hand, you do accelerate it to whatever initial velocity you're able to. As soon as it's released, it has that initial velocity and the acceleration from then on is provided by gravity alone.

Answer 6

The acceleration is a constant, pointing downward, always.
The initial velocity,can be in any direction, it would not affect the g.

Answer 7

whilst the article is on your hand the acceleration could be diverse (consistent with probability larger) controlled via the acceleration of your hand. as quickly because it rather is released out of your hand the acceleration might exchange to the 9.8 m/s^2 by way of gravity.
