It is accomplished by the action of a force. And it’s a scalar quantity but is made up of two vectors (A) & (B)
Work W=F×d
Work in component form
W=Fxdx + Fydy + Fzdz
Work in magnitude-angle form
W= F × d × cos @
Kinetic energy is?
Potential energy is?
- is the energy that makes object move
-is the energy that is stored within an object
To get magnitude of A and B use?
Pythagorean theorem for both a and b
To get magnitude use ?
The formula of magnitude - angle form
If theta @ is 0 its
Work isPositive, directly helping the motion
If theta @ is 90° its
There’s no work usually just goes curve it’s perpendicular to the force.
If theta @ is 180° its
Work is Negative, it opposes the motion.
Work energy theorem formula
W=∆KE=0.5 mv^2
∆KE = TO WORK
GPE Gravitational potential energy formula
U=mgh cause it depends on height.
EPE Elastic potential energy formula
U=0.5kx^2 cause it’s spring
