Is a trebuchet a Force Magnifier or a Distance Magnifier?
I'm unsure as to what exactly a distance magnifier is so hopefully someone with expertise in trebuchets can add to this. However I am confident that a trebuchet works on the principle of a lever. A lever is a force magnifier. Yet a trebuchet also uses a sling to launch the projectile in a parabolic arc which has the effect of increasing the distance, so perhaps it qualifies as both? A lever is most often used as a force multiplier, where the load moves through a smaller distance than the applied force, but in the case of a trebuchet the lever is used in the opposite sense. The load moves through a greater distance than the applied force and so the trebuchet is a distance multiplier.
Is a wheelbarrow a force multiplier?
a froce magnifier
Does a doorknob increase force when a hand turns it?
yes
How would the force needed to open a door change if you put the handle in the middle of the door?
If the doorknob were moved to the middle of the door, it would take twice as much force to open it than if it were at the edge of the door. With the mass of the door being equal. Moment = the force to open the door times the distance to the center of the hinges. If the distance were cut in half it would take twice the force to keep the equation true.
What force holds an object in a circular object?
Centripetal force is necessary to keep an object in a circular path.
Is a crowbar a Force Magnifier or a Distance Magnifier?
Force magnifier... It's basically a lever which pivots around the sharp bend in the metal. This amplifies the force applied to the long arm.

What is a force produced by a circular motion that causes something to accelerate?
Circular motion doesn't produce force. 'Centripetal force' is necessary in order to produce circular motion. Also, so-called 'centrifugal force' isn't a force at all.
What force holds an object in a circular object?
Centripetal force is necessary to keep an object in a circular path.
Does centrifugal force exist?
No, centrifugal force is fictitious force, peculiar to circular motion, that is equal but opposite to the centripetal force that keeps a particle on a circular path.
Why radial force doesn't work on orbit in circular motion?
Radial force doesn't work on orbit in circular motion.ÊCentrifical force is created by objects going in a circular motion, where as there can be no balance of the forces.
What force moves in a circular motion?
Centrifical force.
What is origin of the centripetal force that keeps a body in a circular path?
The centripetal force that keeps a body in a circular path around another body is called gravity. It is one of the four fundamental forces, the other three being the strong interaction, the electromagnetic force, and the weak interaction. Gravity is the weakest of the four in terms of force, but it is the strongest of the four in terms of distance.
What is the force on an object pulling toward then center of a circular path?
Centripetal force is the force toward the center of a circular path. It is often confused with centrifugal force, which is the force away from the center.
