The road, pushing against the tyres.
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.

80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
=(mv*v)/r =(2000*25*25)\80 =15625N
Force is given by Newton's second law: F = ma where F is the force, m is the mass and a is the acceleration. F=2000kg x (25 m/s)2 / 80 meters 15,625n
The gravitational force between Earth and the Sun provides the centripetal force needed to keep Earth in orbit. This force keeps Earth moving in a circular path around the Sun.
When you're driving in a car and turn a corner, centripetal force from the door of the car helps you move along the circular path of the corner.
The tension in the string provides the centripetal force for the mass in uniform circular motion in this experiment. This tension acts towards the center of the circular path, keeping the mass moving in a circular motion instead of following a straight line.
The weight of the masses provides the force necessary to keep the masses moving in a circular path, which is the centripetal force. This is due to the tension in the string providing the centripetal force required for circular motion, balancing out the weight of the masses. Thus, one can consider the weight of the hooked masses as equal to the centripetal force in this setup.
1. Whirling of a stone tied to a string: The string provides necessary centripetal force for the rotation of stone.2. Turning of vehicles in a circular track: The friction due to the tyres in case of levelled road and the angle of inclination of tracks in case of banked tracks provides the necessary centripetal force.
centripetal force
The tension in the string provides the centripetal force needed to keep the stopper moving in a circle. This tension pulls the stopper towards the center of the circle, maintaining the circular motion.
Centripetal force is the force that keeps an object moving in a circular path. Centripetal force always acts in the direction of the center of the circle. Centripetal force is a real physical force that pulls objects radially inward. Centripetal force is necessary to maintain circular motion.
An object in orbit needs a centripetal force to keep it moving in a circular path. Gravity provides this centripetal force, pulling the object towards the center of the orbit. Without this force, the object would continue in a straight line tangent to the orbit.
Centripetal force always acts inward towards the center of rotation. Centripetal force is required to keep an object moving in a circular path. Centripetal force is a real physical force acting on an object in circular motion. Centripetal force can be provided by tension, friction, or gravitational attraction.
Basically, the centripetal force CAUSES the circular motion in the first place. In other words, without a centripetal force, the moving object would just go straight ahead.
The centripetal force is always perpendicular to the motion in circular motion. It acts towards the center of the circle, keeping the object moving in a circular path.
