What else can I help you with?
If you push a box forward and the box moves forward you have done work.?
Work, more specifically "positive" work because the box moved in the direction in which the force was applied.
How does work increase force?
Work is done when a force is applied to move an object over a distance. Increasing the force applied to an object will increase the amount of work done, as it requires more energy to move the object against a greater resistance. This increase in force results in more work being done on the object.
What must occur for work to be done on an object?
Formally, energy is required to do work. Work is technically force times distance. Thus, what must occur is a force must be applied to an object and the object must move with some movement being in the direction of the force. The quantity of work done is the "dot" product of the force vector and displacement vector. To carry out work "on an object" or in any fashion requires the same amount of energy be used as the amount of work done. (Of course, friction and other inefficiencies result in the use of more energy than the actual work done, with the excess energy taking some other form, such as heat.)
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.
Is work directly or inversely proportional to force?
Work is directly proportional to force; the amount of work done on an object is directly related to the force applied to it. More force results in more work being done.
Is more work done when a force of 2N moves an object 3M or when a force of 3N moves an object 2M?
Work = (force) x (distance) (2 x 3) = (3 x 2) The work in the two cases described is equal. The answer is "no".

When force is to the direction of motion no work is done?
No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.
What type of friction occurs when an object moves through a liquid of gas?
The type of friction that occurs when an object moves through a liquid or gas is called fluid friction, or more specifically, drag force. This force opposes the motion of the object due to interactions with the molecules of the fluid, causing resistance.
How the force of air resistance deponds on an objects speed?
The force of air resistance increases with an increase in the speed of an object. This is because as an object moves faster through the air, it encounters more air particles, leading to more collisions and thus a greater air resistance force acting on the object.
What happens to the weight of an object when it moves farther away from the centre of the earth?
The weight of an object decreases as it moves farther away from the center of the earth due to the inverse square law of gravity. This means that the gravitational force acting on the object weakens as the distance increases.
If there is more friction what happens to a moving object?
If there is more friction, the moving object will experience more resistance, causing it to slow down or require more force to maintain its speed. This can lead to increased heat generation due to the energy lost to friction.
Lowering an object decreases its potential energy?
Yes, when an object is lowered, it loses potential energy and increases kinetic energy as it moves closer to the ground. This is due to the force of gravity acting on the object as it moves to a lower position.
