Force changes either the speed or the direction of motion, or both.
Force can change the direction of a moving object when applied appropriately.
Any force that's not in the direction that the object is moving
or directly opposite to it, will change the direction of its motion.
the exertion of another force
which pulley changes the direction of force
A fixed pulley changes the direction of the force.
It changes the direction of the input force only
The combined changes in an object's speed and direction when force acts on it is called "acceleration".
gear-box
changes the direction of a force
which pulley changes the direction of force
when it changes its direction
A fixed pulley changes the direction of the force.
It changes the direction of the input force only
The combined changes in an object's speed and direction when force acts on it is called "acceleration".
centripetal force
... direction of a force.
Friction
The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
A force.
if only the direction changes,the input force will be the same as the output force.the mechanical advantage will always be 1.
