Never Calculate Work wrong again!

This video tutorial explains the concept of work as the transfer of energy that causes an object to move. It outlines the conditions necessary for work to be done and introduces the formula W = FD, where W is work in joules, F is force in newtons, and D is distance in meters. The tutorial also demonstrates how to use a triangle method to simplify solving the formula and provides examples of calculating work, force, and distance.

What are the two conditions that must be met for work to be done?

• The object must move and the force must be applied in the direction of movement.

• The object must be stationary and the force must be applied in any direction.

• The object must move and the force must be applied perpendicular to the movement.

• The object must be stationary and the force must be applied in the opposite direction.

Which formula is used to calculate work?

• W = D / F

• W = F / D

• W = F * D

• W = F + D

If a force of 18 newtons is applied to move a box 2.3 meters, how much work is done?
