- Legacy Problem Set
This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Work and Power Problems. Previous Next. Problem : A 10 kg object experiences a horizontal force which causes it to accelerate at 5 m/s2, moving it a distance of 20 m, horizontally. How much work is done by the force? The magnitude of the force is given by F = ma = (10) (5) = 50 N.
The Extra Problems pertain to various aspects of the topic of work, energy, power, the work-energy relationship, and the conservation of mechanical energy. The problems are divided into six separate sets of problems.
Energy is defined as the capacity to do work and comes in different forms: Gravitational potential energy - this is dependent on the object’s position in a gravitational field and its mass. It increases as an object’s height above the ground increases.
On the following pages you will find some problems of work and energy with solutions. Try to do them before looking at the solution. Work and Energy - Work done by a constant force. Work and Energy - Work done by the weight force and potential energy.
