Work done by force – problems and solutions 1. A person pulls a block 2 m along a horizontal surface by a constant force F = 20 N. Determine the work done by force F acting on the block.
Follow along with common work and power example problems and solutions. See how to solve problems when force is applied directly parallel or at an angle.
Solved Example Problems for Work done by a constant force. Example 4.2. An object of mass 2 kg falls from a height of 5 m to the ground. What is the work done by the gravitational force on the object? (Neglect air resistance; Take g = 10 m s-2) Solution. In this case the force acting on the object is downward gravitational force . This is a ...
We have 20 ready-to-use problem sets on the topic of Work, Energy, and Power. These problem sets focus on the use of energy principles to mathematically analyze systems involving the motion of objects.
This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
How much work do you do to move the child from \(\theta=0\) to \(\theta=\theta_1\)? Use a detailed diagram to show that the work done by \(\vec F\) is equal to \(mgh\), where \(h\) is the change in height of the child.
