if you keep the centripetal force the same but increase the radius, what happens to the object's speed?
2)A centripetal force F is applied to an object moving at a currant speed vin a horizontal relea speedvin a horizontal circle of radius r. If the radius is quadrupled and the speed is doubled, what happens to the centripetal force? 2v (A) Increased by a factor of 2 (8) decreased by a factor of 2 (C) doesn't change (D) increased by a factor of v2 Y 2
What happens to centripetal force when speed decreases, in the special case that the object continues moving in a circle of the same radius? a)The force increases. b)The force sometimes stays the same and sometimes decreases. c)The force also decreases. d)The radius cannot stay the same.Speed does not affect centripetal force.
The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...
The centripetal force on an object of mass m moving in a circle of radius r with a speed v is: ? = (??^2)/? . Determine the centripetal force and uncertainty for m = 0.80 ± 0.02 kg, r = 1.22 ± 0.02 m, and v = 10.1 ± 0.2 m/s.
1. Calculate an approximate value for the centripetal force acting on the Earth due to the sun. Assume the Earth travels on a circular path about the sun (in reality its slightly elliptical) and use the average Earth-Sun distance in your calculation. What familiar force is acting as the centripetal force in this situation? 2. In this experiment, what familiar force is acting on as the centripetal force on the object undergoing circular motion?
The centripetal force exerted on a 2.0kg object moving along a circular path of radius 3.0m is 12N. What is the magnitude of its velocity?
An object performs circular motion. If the mass m is doubled as well as the speed, but the radius is kept constant, then the centripetal force is multiplied by a factor of: A) 4 B) 8 C) 6 D) 1
A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...
3. Distinguish between. centripetal force and centrifugal force. Explain in what direction each force t acting and on what it is acting. 32 4. Calculate at what speed the earth would have to rotate in ordet that objects at the equator would have n weight. Assume the radius of the earth to be 6400 kilometers. What would be the linear speed of a point o the equator? What would be the length of a day (time from sunrise to sunset)...
