What does effort forces mean?
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.
What is the term for the force of gravity on an object that needs to be lifted?
This is usually called its weight.
Why are the objects easier to push or pull than others?
An object with a greater mass needs more force. Mass is what gives an object resistance to acceleration. Newton's Third Law: force = mass x acceleration, or acceleration = force / mass.
What does a pulley cause?
When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.
Relationship between force and motion?
An object will only change its motion if undergoing a force acting upon it. An object does not, necessarily, need a force to act upon it to move; it needs only a force to accelerate (or decelerate!) If dealing with an object at rest, this equation works best to describe how that object can begin to move: F = ma Where F is the force applied, m is the mass of the object, and a is the acceleration. Therefore, if you apply a force of 10 Newtons to a mass of 10 Kilograms constantly, the object will undergo uniform acceleration of 1 m/s^2 -- ie, it will increase its velocity by 1m/s (meter per second) every second. A force does not need to be constantly applied to an object for it to continue to move. If a force of 10 Newtons is applied to an object of mass 10 kilograms for just one second, the object will accelerate to AND THEN REMAIN AT the velocity 1 meter per second. Now, if you're dealing with objects already moving, the equation looks a little different: it's called the impulse equation, and it describes the relationship between forces and objects in the context of a CHANGE OF MOTION (or, specifically, momentum.) It reads as follows: FT = m(Vf - Vo) F and m are the same as above. Essentially, this equation describes the change in motion--starting at "Vo" and ending with "Vf" of an object mass "m" when the force "F" is applied for "T" seconds. That's really all there is to know--for LINEAR motion, which I assume you're referring. If you mean angular motion, that's another ballgame, and one I really don't want to get involved with ;)

What is the net force a person?
Just as with other object, you can deduce the net force using Newton's Second Law. If an object - a person in this case - is at rest (or moving at a constant velocity), the net force must needs be zero. Only if the person is accelerating will there be a non-zero net force.
If matter moves a force acted on it?
Matter is held down by the force of gravity, like a cup placed on a tabletop. The cup needs either for the table to be tilted, allowing gravity to cause the cup to overcome the force of friction and to slide off the table, or someone needs to push (force) the cup sideways.
How can an object be made to rotate naturally?
An object needs to have some sort of force exerted on it to start rotating. There are no "unnatural" forces, therefore any object made to rotate will have been made so "naturally."
How can an object be put into motion naturally?
An object needs to have some sort of force exerted on it to be put into motion. There are no "unnatural" forces, therefore any object put into motion will have been done so "naturally."

Does work done depends on time what you mean is doing a work in 5 minutes needs more work or doing a work in 10 minutes need more work you mean more newtons?
Newtons is used to measure force, NOT work or energy. It is important not to confuse force with energy (or work). Whether you need more force depends on the exact situation. For example: * When pulling an object in a situation where you have to overcome friction between solids, the force is practically independent of the speed. * When pulling an object through a fluid, the force does increase for a greater speed. * When pulling an object at a constant speed upwards (against the pull of gravity), the force required is independent of the speed (ignoring air resistance).
How do you calculate the work done on a object?
To calculate work done on an object one needs to use the following equation; work = force x distance or W = F x d
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
