Explanation: The formula for work is , work equals force times distance . In this case, there is only one force acting upon the object: the force due to gravity.
What is the formula for work?
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 .
What is work done and how is it calculated?
The formula for work is , work equals force times distance . In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity.
How do you calculate work done by force?
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 is rate of work done?
The SI unit of work done is joule. Now, the rate of work done means the amount of work done per unit time . ... Energy transferred is the same as the work done on the object. So, power can be defined as the amount of work done per unit time or the rate of doing work. The unit of power is watt.

What is current formula?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R . The SI unit of current is Ampere (Amp).
What is normal force formula?
| F_N Normal Force | m Mass | g Acceleration due to gravity |
|---|
What is the force in work done?
When a force acts on an object over a distance , it is said to have done work on the object. Physically, the work done on an object is the change in kinetic energy that that object experiences. ... The SI unit of work is the newton-meter or joule (J).
Is work same as power?
Power is the rate at which work is done . It is the work/time ratio. Mathematically, it is computed using the following equation. The standard metric unit of power is the Watt.
Is work done per unit charge?
A potential difference of 1 V means that 1 joule of work is done per coulomb of charge.
Is work and energy Same?
Work is the ability to supply force and a change in distance to an object. Energy is the ability to supply or create work .
