What is the formula of work done and its unit?
Work done = force × displacement. W = F × s. The SI unit of work is Joule (J).
What is the unit for work done?
joule
Scientists use the joule to measure work. One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force.
Why the unit of work is joule?
joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
What is work and example?
Work is force applied over distance. Examples of work include lifting an object against the Earth’s gravitation, driving a car up a hill, and pulling down a captive helium balloon. Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton – meter (N · m).
What is work done explain with example?
The work done by a force can be defined as the product of the displacement of an object and the component of the applied force which is in the direction of the object’s displacement.
What is the formula of work done class 9?
Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. 1 Joule = 1 Newton × 1 metre. The unit of work is joule.
What is work done 10th?
The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. Formula. Work can be calculated by multiplying Force and Distance in the direction of force as follows. W = F × d. Unit.
What is work done give its formula?
To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
Which of the following is an example of work done?
Examples: Pushing a car horizontally from rest; shooting a bullet (the powder does the work); walking up stairs; sawing a log.
