A force perpendicular to an object's motion.
Examples include:
-- the gravitational force on an object in a circular orbit
-- the gravitational force on a car that's moving on a level road
-- the tension in the string holding a yo-yo as it spins in a circle around your head.
Centrifugal force.
Mechanical energy is transferred by a force to a moving object.
b. Work is a force that moves an object. It is defined as force applied over a distance in the direction of the force.
No! An example would be. If U tryed to push a wall, Ur applying force but no work is being done!
I usually start with the definition of work: Work = force * distance so... Force = work / distance Distance = work / force So, no. You had it backwards.
Simple
No. A force has to be applied through a distance before it becomes energy.
Work is energy, and work done by a force equals force times distance moved IN THE DIRECTION OF THE FORCE
Force that did the work = (work done) divided by (distance the force acted through)
Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.
A type of machine that changes the direction or amount of force needed to do work is called a simple machine. Examples include levers, pulleys, and gears. These machines help make tasks easier by altering the force needed to accomplish them.
Input work refers to the work done on a machine, which is calculated as the input force multiplied by the input distance. Output work is the work produced by the machine, which is calculated as the output force multiplied by the output distance. The efficiency of a machine is determined by comparing the output work to the input work, with ideal machines having an efficiency of 100%.
