No, a catapult works on the principle of stored mechanical energy that is released to propel an object. Frictional force plays a minimal role in the functioning of a catapult as the stored energy is primarily converted into kinetic energy for the launching of the object.

What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
Which frictional force is self adjusting force?
The static frictional force is a self-adjusting force. It increases or decreases to match the applied force, preventing the object from moving until the maximum threshold is reached.
What has frictional force needed to start an object at rest into motion?
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
Will the kinetic frictional force change if you pull with the same applied force at a new angle?
Yes, the kinetic frictional force will change if you pull at a new angle. The frictional force is influenced by the component of the applied force parallel to the surface. Therefore, changing the angle will alter this component and affect the kinetic frictional force.
What frictional force?
Frictional force is the force that opposes motion between two surfaces.
Which force do not work on the body on which it acts?
frictional force
What is the sign of the work done by the frictional force?
The work done by the frictional force is negative because the force opposes the direction of motion. This means that the frictional force removes mechanical energy from the system by transforming it into heat, resulting in a decrease in the object's kinetic energy.
Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.

What is the resistance force of frition?
Frictional Force
What relationship exists between the static frictional force and the normal force of an object?
The static frictional force is directly proportional to the normal force acting on an object. As the normal force increases, the maximum static frictional force that can be exerted on the object also increases.
What forces are involved in catapults?
Gravity and air resistance are key forces acting on most catapults. Depending on the type of catapult, there will also be either tension or torsion. Both are forms of elasticity. Catapults with torsion acting on them are usually ballistas while catapults with tension acting on them are simply called catapults.
