In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity? When we apply a force to an object and move it in the direction of the force, we say … more
Pulleys with Many Wire
Movable Pulley Movable pulleys can move axes, unlike fixed pulleys. Movable pulleys have the advantage of being able to move with less force. But, the distance that I have to move is longer than the fixed … more
Pulleys with One Wire
Movable Pulley Movable pulleys can move axes, unlike fixed pulleys. Movable pulleys have the advantage of being able to move with less force. But, the distance that I have to move is longer than the fixed … more
