What is difference between work motion and force?
motion is the movement of an object and force is the power or work done to move the object
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.
When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
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."
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.
What two things need to happen for there to be work done on an object?
If he object moves as a force is applied and the direction of the objects motion is the same as the direction of the same force.
What kind of work is done when a force opposes an object's motion watts newtons or molecular?
The answer is newtons
When force is and what direction of motion no work is done?
Perpendicular (90o). Like whirling an object around on a piece of string. The force is along the string, at right angles to the motion.
Wehn a force changes an objects motion work is done?
When the point of the application of the force gets displaced then work is said to be done by the force. Hence whether already the body was at rest or in motion and as the force is applied on the body and the point of application of the force is found to get displaced then certainly some energy would have been utilized to change the state of rest or of uniform motion and so work is done.
Differentiate batween the work done on the body and work done by the body?
note: Work done is = force applied to a body * time taken by the body When we apply a force on to an object such that the object displaced in the direction of force, then some unit of work is done on the body. When a body sets another body into motion by applying a force, in unit time, that body is considered as it had done a unit of work
How is work done in different situation?
Work can be completed in three different situations: when force is present, when force is applied to a particular object, and when the force applied occurs in a parallel motion.
What is done when force makes an object move?
When a force makes an object move, work is done.
