How work done can be measured?
work done is measured in joules (J) distance moved along the line of action of the force is measured in metres (m)
What two factors determine the amount of work done?
1) The force applied to the particular object. 2) The exact distance in which the body is displaced.
What is the measure of work in physics?
Joule
In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work.
How do we calculate work done by a force write any two conditions under which work done by a force is zero?
1. When there is no force or no displacement.. or the direction of displacement is perpendicular to the direction of force then the work done is zero. 2. When the displacement is zero OR when the force acts at right angles to the direction of the displacement then the work done is zero.
What factors affect the amount of work done on an object?
Calculating work done The amount of work done when a force acts on a body depends on two things: the size of the force acting on the object. the distance through which the force causes the body to move in the direction of the force.
How is the work done by a force measured when force is in the direction of displacement?
i) is in the direction of displacement. That is equal to Force x Displacement of the point of application of the force in the direction of force. ii) Work done by a force when the force is at an angle θ to the direction of displacement , = Force x component of displacement in the direction of force.
How can you find the work done from the above graph?
From a force-displacement graph we can:
- Read forces directly from the graph.
- Read displacements directly from the graph.
- Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.
What are the factors that determine the work done?
The work done on a body depends upon two factors:
- Magnitude of the force (F), and.
- The displacement through which the body moves (s).
How do you calculate work done on an object?
Calculating work done. To calculate the work done on an object when a force moves it, use the equation: work done = force × distance. W = F s. This is when: work done (W) is measured in joules (J) force (F) is measured in newtons (N) distance moved along the line of action of the force (s) is measured in metres (m)
How do you calculate work done by a force?
Work Calculator. Work is the amount of energy transferred by a force and is based on the distance traveled by the object. Use our free online work calculator to find the work done by entering the force and distance.
What is the formula for work?
Where, W =Work F = Force D = Distance Work is defined as the displacement of the object due to a force applied upon the object. Work is done when an object moves in the same direction as the force is applied and also when force remains constant.
What is work calculator?
Work is done when an object moves in the same direction as the force is applied and also when force remains constant. This online Work Calculator helps you find out the work, force or distance based on the other two parameters. Work, force and distance are related to each other.
