WorkThe application of a force to an object and the object’s movement in the direction the force is applied
Work Equation
Work equals force times distance
Work = F x d
ForceA push or pull exerted on an
object.
NewtonA unit of measure that equals
the force required to accelerate one kilogram of mass at a rate of one meter
per second per second.
JouleA unit of work equal to one
newton-meter.
Newton X Meter = Joule

NOT move.
Stationary NOT stationary
Incline PlaneA flat, slanted surface like a
ramp.
GeotropismThe growth that happens in living organisms in response to gravity, such as the downward growth of plant roots.
