What are the two requirements for work to occur?
1 WORK In order for work to be done, three things are necessary: There must be an applied force. The force must act through a certain distance, called the displacement. The force must have a component along the displacement.
How do you calculate quantity of work?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
What are the quantities on which the amount of work depends?
Work done depends on the force applied and the perpendicular distance between the fulcrum and the point of action of force. Both force and perpendicular distance are directly proportional to the work done.
What three things are required for work to be done?
What conditions are required for work to occur?
There are three key ingredients to work – force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.
What type of quantity is work?
Work is a scalar quantity, so it has only magnitude and no direction. Work transfers energy from one place to another, or one form to another. The SI unit of work is the joule (J), the same unit as for energy.
Question 24 What are the quantities on which the amount of work done depends? How are they related to work? Force and distance are related to work done as work-done are directly proportional to the force applied and the distance moved by the body.
What are the three requirements for work?
How do you calculate work without force?
If you push on an object and it doesn’t move, then no work is done. If an object’s kinetic energy doesn’t change, then no work is done. Another Equation for Calculating Work: Work = Mass * Gravity * Height and is measured in Joules.
