What Does It Mean When Work Is 0? The work done by a force is zero if the displacement is either zero or perpendicular to the force. The work done is positive if the force and displacement have the same direction, and negative if they have opposite direction. What is it called when work is
What Are The Two Essential Conditions For Work Done By A Force Acting On An Object? In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. What are the conditions for work done by an object? A. (i)
What Is Positive Work In Physics Class 9? When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as
What Is Example Of Negative Work? Negative work is performed if the displacement is opposite to the direction of the Force applied. Example: Work was done the gravity on a rocket going perpendicular upwards. What is meant by negative work give one example? NEGATIVE WORK: The work done is said to be negative work when
What Is The Basis In Choosing A Situation Where Work Is Done? Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves
