When can we say that work done is zero?
Zero work is done when the displacement of a body is zero or perpendicular (θ=900,cosθ=0) to the direction of force applied, then work done is zero. For example, if a person tries to push a wall, he is applying force yet the wall does not move, so the displacement of the wall is zero, and hence work done is zero.
What does it mean when work is 0?
The work is zero when there is no displacement of the object along the line of force. So if for example you have a heavy wooden crate and you’re trying to push it and you’re not able to, the work done by you is zero even though you’re applying a force.
What is zero work done with example?
1) A simple example of zero work is when you stand holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and also the gravity is zero.
When can we say work is done?
Work is said to be done when the force is applied on an object and it moves through a distance in the direction of application of force.
What is no work in physics?
No work, as understood in this context, is done unless the object is displaced in some way and there is a component of the force along the path over which the object is moved. Holding a heavy object stationary does not transfer energy to it, because there is no displacement.
What is zero work done Brainly?
Work done is said to be zero when force applying to the body is zero or the Displacement done by body pic zero. if the value that means force acting on body is perpendicular then the force acting will be equals to zero.
Why do we say that work is done class 9?
1. When do we say that work is done? Answer: Work is said to be done whenever a force acts on a body and there is a displacement of the body caused by the applied force along the direction of the applied force.
What is no work done?
Can work be done if there is no motion explain?
Question: 1 ) Can work be done on a system if there is no motion? ( Yes, if an outside force is provided. Yes, since motion is only relative. 2) If you walk 5 m horizontally forward at a constant velocity carrying a 10 N object, the amount of work done by the force.
