What happens when you exert force on an abject and it exerts force on you?
According to Newtons 3rd law, "Every action has an equal and opposite reaction". if you exert force on an object, the object will exert an equal and opposite force on you. when the forces exerted by you and the object balance a state of equilibrium is attained. however if you exert a force greater than the weight of the body, the body begins to move and work is done.
Is work done when you throw a ball?
Yes, throwing the ball requires a force, and work is done when a force moves a mass over a distance.
In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
When a ball rises vertically to a height h and returns to its original point of projection the work done by the gravitational force is?
The work done would be calculated by 2mgh. The force on the ball is calculated by mg, and work done is by Fd, where d is 2h (the force acts on both upwards height and downwards height, thus twice the distance).
When moving a couch you exert a force of 400 N and push it 4 m. How much work have you done?
Work = Force x DistanceWork = 400 x 4 Work = 1600 Nm Work = 1600 Joules Work = 1600 J
How much is done if you exert a 25-N force to lift a ball 0.4 m in 2 s?
10 J (novanet)

If you exert a force of 10 to lift a box of .9m how much work has been done?
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
When a ball is in the air is work being done?
If the ball is falling, then work is being done.Work is the product of (force) times (distance). The ball in the air has force acting on it, created by gravity, and known as the "weight" of the ball. If the ball is falling, then the work done on it by gravity is (its weight) multiplied by (the distance it falls).If the ball is accelerating up, then something has to be providing force greater than its weight, in order to lift it against the force of gravity. It may be a muscle, a motor, an elevator, or some kind of air-foil taking energy out of wind. The work done on the ball is (the upward force on it) multiplied by (the distance it's lifted).If the ball is moving only horizontally, and not the slightest bit up or down, then almost no work is being done, since there's no significant horizontal force acting on it. The ball does a small amount of work to move air as it moves through the atmosphere.

Which is A 2 kg ball is thrown upward with a velocity of 10 m s What is the work done by gravity when the ball reaches its maximum height?
force = mass * acceleration = 2 * -9.82 = -19.64 newtons work done = force * distance = -19.64 * 5.092 metres = -100 joules
When moving a couch you exert a force of 400 N and push it 4 m. How much work have you done?
Work = Force x DistanceWork = 400 x 4 Work = 1600 Nm Work = 1600 Joules Work = 1600 J
You exert a force of 75 newtons on a rock. You push and you push, but you can’t budge it. You are exhausted! How much work did you perform?
Unfortunately, 0. The rock has 0 displacement, so despite force being exerted no work was done (at least in physics terms).
If you exert a force of 10.0 n to lift a box a distance of 0.9 m how much work do you do?
Work done equals force times distance, so 10.0 times 0.9 is 9 joules.
