What force is needed to accelerate an elevator with a mass of 1000 kg downward?

-- No force is needed to accelerate any mass downward. Just let it go,
and watch it accelerate downward at 9.8 meters per second2.
-- To accelerate a 1,000-kg mass upward from the Earth's surface, just
push it up with any force greater than 9,807 newtons (2,204.6 pounds),
and make sure it's not rubbing on anything and there are no other forces
on it trying to hold it down.

∙ 8y agoForce = mass * acceleration
Since the only force acting on the elevator is gravity, the force is
1000*9.81 = 981N Towards the ground
Note that it is essential to put the direction that the force is acting as it is a vector quantity.

∙ 10y agom= 1,000kg
a=9.8m/s2
f=? > 1,000*9.8= 9,800

∙ 9y agoSimply it will be got by M g. Here M = 1000 kg and g = 9.8 m/s^2
So force F = M g = 9800 N

∙ 8y agoGravity is the force. If you wanted to know the magnitude of the force, "weight" is measured in force units, a 1000 kg elevator weighs 9800 newtons.

∙ 7y agoThere is no net force in free fall so force is zero
Wiki User
∙ 6y agoThe force, in this case, is the force of gravity.This force is also called "weight"; you can calculate it as the mass times the gravitation. The answer will be in newton.

∙ 6y agothe force of gravity is mass x acceleration which is 9800 Newtons. However in free fall you experience zero gravity until you hit bottom.

After the diver jumps forward from the diving board the force of gravity will accelerate the diver parallel to the direction of motion?
No. It will accelerate the diver downward only.
How can a bicycle seat exert a force?
If you sit on it, you push downward. The bicycle seat naturally pushes back up - if this wasn't the case, you would accelerate downward, due to the force of gravity.
What are the two forces acting on you in an elevator?
1). The force of gravity attracts you downward. 2). The floor of the elevator car exerts an upward force on the bottom of your feet. When #1 is greater than #2, you accelerate downward, and you feel lighter than normal. That happens when the car is starting to go down, or finishing going up. When #2 is greater than #1, you accelerate upward, and you feel heavier than normal. That happens when the car is starting to go up, or finishing going down. When #1 and #2 are equal, you don't accelerate at all, and your weight feels normal. That happens when the car is standing still, or rising at a steady speed, or dropping at a steady speed.
How much force is needed to accelerate your body at a rate of 2 if you weigh 45 kg?
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.
What force is needed to accelerate a box with a mass of 5 kg to an acceleration of 3 ms2?
The force required is 15 Newtons.
What force is needed to accelerate an elevator with a mass of 1000 kg upward at a rate of 2 m per second squared?
Weight of the elevator = 1000kg x -9.8m/s2 = -9800N Upward force acting on the elevator = 1000kg x 2m/s2 = 2000N Net force = upward force - weight of elevator = 2000N - (-9800N) = 11800N
What happens if gravity is the unbalanced force?
The object will accelerate in a downward direction.
How accelerate change when third force act in downward direction?
Then - according to Newton's Second Law - you would have more acceleration downward.
After the diver jumps forward from the diving board the force of gravity will accelerate the diver parallel to the direction of motion?
No. It will accelerate the diver downward only.

When is an objects to be in free fall?
In free fall, the force of gravity alone causes an object to accelerate in the downward direction.
What minimum downward force needed to lift the 120 Newtons weight?
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
The force that is needed to move somethimg is proportional to what?
The force needed to accelerate an object at some rate is proportional to the object's mass.The object may be moved by as small a force as you want. It just won't accelerate at a very high rate.
How much force is needed to accelerate an object twice as fast?
You twice it.
How much force is needed to accelerate your body at a rate of 2 if you weigh 45 kg?
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.
What force in newtons is needed to accelerate a 2kg mass at 7 ms squared?
