If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less 9.8 meters per second?

Whether the object is dropped, thrown downwards, thrown upwards, or thrown horizontally,
its downward acceleration is the same 9.8 meters per second2.
If it's thrown downwards, however, its speed at any instant is greater than the speed at the same
instant would be if it had only been dropped, since it has some speed before the acceleration begins.

Can anything ever have a downward acceleration greater than g?
Yes, objects can accelerate at a rate greater than "g". Most objects, when falling in the absense of air resisitance, accelerate at a uniform rate of -9.81 m/s^2 (this is under ideal conditions on Earth). Air resistance tends to decrease that acceleration. The classic example of greater than "g" acceleration is a bungee jumper.
If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less?
It's initial acceleration (when it is still in your hand) will be greater than that of a free falling object. However, once it leaves your hand, there are no other forces other than gravity acting on it (neglecting air resistance), so a thrown object will accelerate at 9.8 meters per second squared.
How the tension can be greater than gravity yet the elevator is moving downwards?
The extra tension depends not on the velocity of the elevator, but on its acceleration.
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
No.Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.
What is the given name for the force of gravity acting on you?
It is your weight, which manifests as a downward force exerted by your body, although it is also an acceleration to a greater force if you fall.

When the net force an object is greater than zero the object will accelerate in the direction of the?
The acceleration will be in the direction of the net force.
why does an object with less mass have larger acceleration?
Whenna given force is applied ,an oobject with greater mass will accelerate less

Second law of motion?
Second Law of Motion: Acceleration is produced when a force acts on a mass. the greater the mass ( of the object being accelerated) the greater the amount of force needed ( to accelerate the object).
What is the relationship between forcemassand acceleration?
To get something t accelerate, you must apply a force to it. To get it to accelerate faster requires more force. Also, if something has a greater mass, it requires more force to get the same acceleration as something of lesser mass. Leave a note on my message board if you would like some formulas relating to mass, force, and acceleration.

What is deceleration uniformly accelerated?
It would be acceleration or deceleration, depending on whether the acceleration is greater than the deceleration or vice versa. dvA/dt = acceleration -dvD/dt = deceleration If you accelerate an object being decelerated, then the act is ( dvA - dvD )/dt
A net force greater than zero will cause an object to?

If a rocket's thrust is greater than it's weight what will happen?
If a rocket exerts a greater downward force than the force with which gravity pulls on, it will accelerate upwards.
