What is the definition of Work Done?
The product of the force and the displacement in the direction of the force
Work Done quantifies the energy transferred when a force acts over a distance.
What does Elastic PE stand for?
Stored energy due to the body’s deformation (stretching or compressing)
Elastic Potential Energy is associated with the position of an object in a force field.
What is KE in terms of physics?
The ability of a mass to do work due to its speed
KE stands for Kinetic Energy.
What does the Work-Energy Theorem state?
The net work done on a body is equal to the change in KE of the body
This theorem is fundamental in understanding the relationship between work and energy.
What is the Principle of Conservation of Energy?
Energy can neither be created nor destroyed, but it can be transformed from one form to another
This principle is a key concept in physics, emphasizing the constancy of energy in isolated systems.
Define Power in a physics context.
Rate of Work done / rate of Energy converted
Power measures how quickly work is done or energy is transferred.
What does Efficiency refer to?
The ratio of useful energy output to the energy input, expressed as a percentage
Efficiency indicates how well energy is converted from one form to another.
Fill in the blank: Work Done is the product of the force and the _______.
[displacement]
The direction of the displacement must align with the direction of the force for work to be done.
