That force is transferred to lift and throw soil using shovel. A lever is a simple machine that consists of a rigid bar kept at one point, known as the fulcrum.
A force called the action force is applied at one point on the lever in order to move an object, known as the opposition force, located at some other point on the lever. A common example of the lever is the crow bar used to carry a heavy object such as a rock. To use the crow bar, one end is put under the bar, which is kept at some point (the fulcrum) close to the rock.
<h3 /><h3>How are forces transferred?</h3>
Bigger pushes and pulls cause more important changes in an object's motion or shape. When objects collide, communication forces transfer energy so as to change the objects' motions. When two objects interact, each one exerts a force on the other, and these forces can transfer energy between them.
