the crowbar is a simple lever. the fulcrum is the round neck. it works like a teeteer-totter, where the kid going down on one end is what pushes up the kids on the other end. the neck is closer to the work and the handles sticks out a much further distance, this gives you the mechanical advantage.(:
A crowbar changes force whenever you lift the crowbar handles up and then put the crowbar handles back to the ground!!!!!

In order to change direction, the applied force (represented as a Vector) must change DIRECTION. A change in magnitude of the Force is not necessary.
Pulleys change the direction of a force.
The answer is force because Force is needed to change the direction of a moving mass.
Force changes either the speed or the direction of motion, or both.
when it changes its direction
No it does notIt may change direction but obviosly it cannot exert you force
Strictly you should ask whether a force can change the direction a body is moving in. The answer is yes.
the force, otherwise the rock would not move.
If the work that they want to do is not being accomplished, they may want to change the direction of force. They may also want to change the direction of force due to space constraints.
Forces cause motion or the change in motion.
