β 11y agoThe force acting on the can when it is whirled in a circular path is centripetal force. This force always acts towards the center of the circular path, in this case toward the person's hand holding the string. This force is necessary to keep the can moving in a circular path instead of flying off in a straight line.
To whirl means to turn around. Here are some sentences.If you whirl around and around, you will get dizzy.The top will whirl quickly around when you turn it.He whirled to look behind him.
A whirlpool typically rotates in a circular motion due to the force of water currents or air flow. The spinning motion creates a vortex that draws surrounding water or objects towards its center. Whirlpools can form naturally in oceans, rivers, or lakes, and can also be created artificially in some water features or appliances.
Whirling a hammer with a longer chain requires more force due to the increased inertia of the longer chain, making it harder to achieve the necessary speed and control to keep the hammer moving in a circular motion. The weight of the hammer at the end of a longer chain also creates a larger centripetal force that needs to be countered by the person whirling it, adding to the difficulty.
Whirlwind
Well, whirling isn't but i think whirl probably is :)
follow a straight -line path
When we tie a stone to a string and whirl it, it moves in a circular path.If the velocity becomes too high then the stone changes to a mass of electrons.It starts radiating energy and ultimately falls in our hand.the energy emitted by the stone is given by E = hv.Where h is Plancks constant and v is the radial velocity of the stone.
For circular motion to occur, there must be a centripetal force( a force that is always directed towards the centre of the circle). The centripetal force is defined as F = mv2/r Where F is the centripetal force, m is the mass of the orbiting body, v is the velocity of the body, and r is the distance to the centre of the circle. If you whirl a conker above your head, the centripetal force is provided by the tension of the string. For a planet orbiting the sun, the centripetal force is provided by gravity.
If you suddenly let go of the rope, the brick will move in a direction tangent to the circle at that point. The only cause of circular motion is centripetal force which is tension of string or indirectly force of hand in this case. As soon as you vanish it, no circular motion is possible and projectile motion is performed.
The word "whirl" can be classified as a noun or a verb. As a noun, it refers to a rapid rotating or spinning motion. As a verb, it means to move or spin quickly and in a circular motion.

There is no such English word for whirld. If you meant "whirl" then this mean turning in a circular motion. Similar to spinning.
Optical illusion.
Yes, the word 'whirl' is both a noun (whirl, whirls) and a verb (whirl, whirls, whirling, whirled).Examples:The star made her entrance in a whirl of excitement. (noun)The propeller began to whirl then the helicopter began to lift. (verb)
Whirl is a verb.
spin is turning and whirl is the same.
Centripetal force is not very difficult to understand, yet most people make it seem overly complex. Centripetal force is an inward force applied to an object that is in circular motion (uniform circular motion). This inward force is what centripetally accelerates an object, which means the object is accelerating around the circle. DO NOT EVER BELIEVE THAT THERE IS A CENTRIFUGAL FORCE. THIS FORCE IS FAKE, BECAUSE THERE IS NO FORCE THAT IS PUSHING OUT ON OBJECT TRAVELING IN UNIFORM CIRCULAR MOTION!!!!!!!!!!!!! All it means is that there is no centripetal force to stop an object from moving out of the circle. An example is a car. If you are sitting in a car, when you go around a bend at a pretty decent speed, you seem to lean in the opposite direction of the turn. this is actually false. you are travelling in a straight line due to your inertia. When the car turns, you continue in that straight line, obviously you don't fly out of the car, because the car applies an inward force on you when you hit the side to keep you centripetally accelerating. Friction is one of the few forces that can stop an object from centripetally accelerating. when i mentioned a straight line due to inertia, I am talking about the velocity of the centripetally accelerating object. This velocity vector is tangent to the circlular path of the object. So that means that if you wanted to whirl a rope over your head like a cowboy and throw a rock at something, you would have to let go of the rope when it was perpendicular to the target. target------------------{((()))}------------------ | | ------- | rock O
