Day 6 - Work done and Power Flashcards
It is done on an object when a force causes displacement
Work
What is the formula for Work?
W=Fd
W=Fdcos
If work is + meaning? and if work is - meaning?
\+ = same direction - = opposite direction
This is the rate at which work is done
Powerq
What is the formula for Power?
P=w/t
It is the ability to do work which can be stored of measured in many forms. It can also be potential of kinetic
Energy
This is static energy.
Potential Energy
What are the types of PE?
Gravitational
Internal
Elastic
This PE is available but not actually being used at the moment such as chemical energy that is capable of being released in combustion
Internal Pe
This PE is stored due to deformation by an elastic object
Elastic PE
This energy is in motion and can be measure through work done on an object in motion and work the moving object will do in coming the rest
Kinetic Energy
This energy present in an object that is due to object’s motion/position. It is the sum of KE and PE.
Mechanical Energy
