How do I calculate work?

The formula for calculating work is Work = Force x Distance . Hence, to calculate the distance from force and work, proceed as follows: Determine the work done, W , when the force, F , is applied. Divide the work done, W , by the applied force, F ..

How do you divide time?

How to Divide Time

  1. Divide each unit of time by the divisor.
  2. Then, working from largest to smallest unit of time, convert any decimal values to whole numbers shifting the decimal amount to a smaller time unit.
  3. If days has a decimal, keep the whole number as total days and convert the decimal to hours.

What is work measured in?

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.

How do you divide hours and minutes?

There are 60 minutes in 1 hour. To convert from minutes to hours, divide the number of minutes by 60. For example, 120 minutes equals 2 hours because 120/60=2.

How do I calculate time in hundredths in Excel? Multiply your times by 24. For example, if cell A1 has 4:15 then =A1*24 will give 4.25. Make sure that the cell containing the above formula is formatted as a decimal. (Excel might automatically convert it to a time-type format so you’ll have to convert it back).

What are the 3 formulas for work?


  • Work = Force • Displacement • Cosine(theta)
  • W = F • d • cos(theta)
  • Power = Work / time.
  • P = W / t.
  • P = F • cos(theta) • (d/t)
  • P = F • v • cos(theta)
  • PE grav = m•g•h.
  • KE = 0.5 • m • v 2

What is work class 11?

Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force. It is measured by the product of the force and the distance moved in the direction of the force, i.e., W = F-S. •

What is work class 9?

Work (W) Work is defined as a force acting upon an object to cause a displacement. It is expressed as the product of force and displacement in the direction of force. W=F x s.

What do you understand by term energy write its SI unit?

Energy can be defined as the ability to do work. The amount of energy possessed by a body is equal to the amount of work it do when its energy is released. Energy is a scalar qauntity. The SI unit of energy is Joule. The energy required to do 1 joule of work is called 1 joule energy.

What do you mean by 1 watt? 1 watt is the power of an appliances which consumes energy at the rate of 1 joule per second.

What can energy do? Energy is the ability to do work

People use energy to walk and bicycle, to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, to light our homes and offices, to manufacture products, and to send astronauts into space.

What are the three formula for work?

Those three quantities are force, displacement and the angle between the force and the displacement. The work is subsequently calculated as force•displacement•cosine(theta) where theta is the angle between the force and the displacement vectors.

What is short answer job?

Answer: Work is defined as displacement of any body in the direction of applied force . Calculated as the product of Force and displacement . S.I Unit is Joule .

What is the old unit of work?

Joule is the old unit of work.

What unit is power?

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).

What is meant by 1.5 hours?

1.5 hours – it is more than the singular ‘hour’. It is another half hour beyond being singular, so it is ‘one AND a half hours’. Doesn’t matter that it hasn’t made it all the way to ‘two’. One is the single hour; the additional half is part of the second hour, so you have two parts of a number.
