From a rock, to a rocket ship, to a galaxy, everything that moves is discussed in terms of force, distance and time. A farmer has 19 sheep All but 7 die How many are left? Take the net force first. Work is a measure of the energy expended in applying a force to move an object. F=MA. Power, with units of watts, is the rate at which work is performed or energy is expended. Work is defined as force times distance. The distance between the objectives is double. Spring rate can also be defined as the estimation of the amount of force needed to compress a spring to a specific distance. But if you suddenly got transported to outer space, the inward pressure of the air pushing on you would be gone, and all that would remain would be the 14.7 pounds per square inch your body exerted outward. C When a force acts on a body that is free to move, the force is the work done by the force divided by the distance moved by the body. Recall what the force exerted per coulomb of unit +ve charge placed at a point represents.. As distance increases using the same method as before the force decreases proportional to the inverse squared. The applied force can be both a contact force or a non-contact force. Pressure is force divided by area. Then the acceleration would increase according the to equation (a=F/m) so the change in force divided by the objects mass will .
