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...

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...

Centripetal Acceleration and Newton’s 2nd Law Lab
Q1. Starting with ar = v ^2 /r, show that for any object moving
in a circle with constant centripetal acceleration ar pulling
inwards, the theoretical rotation period is given by Pth = 2πr v =
2π r ar .
Q2. Does the rotation period change with increased tension in
the way you would expect from theoretical grounds? If you increase
the tension by pulling down on the hanging mass while the rubber...

An object in circular motion requires a centripetal force to maintain that path. What force would be responsible for keeping the bugs on the disk? If you look closely at your results, you will see that the acceleration vectors do not point exactly at the center of the circle. Why is this the case?

Objective: In this lab the Centripetal force required to maintain an object in uniform circular motion will be measured. The relationship between a rotating object's mass, velocity, and distance from the center of rotation to the centripetal force will be tested against theoretical expectations. Equipment: Centripetal Force Apparatus with 1, 2, 4oz weights, Force sensor, Magnetic field sensor, Short lab stand with cross bar, 500 g&1kg counter weights, scissors jack, "C" clamp Background: When an object is in uniform circular motion...

8. 10 Points The figure on the right shows the path of an object. In the region AB and CD, the object moves along a straight line path. In the region BC and DA, the object moves along a partial circular path with radius of R-2.0m and R 3.0m as shown. During the entire time, the object moves with a constant speed of w6.0m/s. For the four point P, p Q, U and V as can be seen in the...

Lab 4: Introduction & Instructions Centripetal Acceleration Introduction Velocity is a vector with both a magnitude and a direction. Since acceleration is a measure of a change in velocity over time, it seems reasonable that either the magnitude of the velocity vector could be changing, or the direction, or both. If magnitude is changing only, then the motion occurs in one dimension and the principles of algebra can be applied to the equations of motion. But suppose the opposite case...

In your reading on two dimensional kinematics, you should have seen that the acceleration of a particle experiencing uniform circular motion is given by: a=v^2/r where v is the speed of the particle and r is the radius of the circular path it is following. What I would like for you to do is a qualitative analysis to help you understand and explain physically why the acceleration has this form. (Please draw images to understand) (a) Compare two particles travelling...

Centripetal problems I would appreciate anybody who answers them. Please show work. Thank you! You find yourself on the Gravitron ride at the county fair. It consists of a circular room in which riders stand against the outmost wall(inside the ride) which spins. At some point, the floor is lowered and riders "stick" to the wall. The ride's radius is 6.0 m and is so popular that many standard human beings of mass 65 kg ride at a time. (a)....
