The force that lifts a load weighing 1 N is 3 N, the lifting height is 5 m. Find the work of this force.

Given:
F = 3 Newton – the force with which the load is lifted;
P = 1 Newton – weight of the load;
h = 5 meters – the height to which the load is lifted.
It is required to determine A (Joule) – the work of force F to lift the load.
Since we are talking about the work of a specific force, the body weight does not matter when solving. To define work, you need to use the following formula:
A = F * h;
A = 3 * 5 = 15 Joules.
Answer: the work of the force to lift the load will be equal to 15 Joules.
