A body rotates with a uniform circular motion. In what situation is the centripetal force greater?...
Explain centripetal force? Think about the difference between uniform and non-uniform circular motion, examples and work done? If a ball of mass 0.5kg does a uniform horizontal circular motion of radius 5.0cm. If the velocity of the mass is 2.0 m/s what will be the tension force, centripetal force and period and frequency?
(b) For an object in uniform circular motion, derive the expression which relates centripetal force to speed. (5 marks] (c) A person swings an object around in a circle on the end of a steel wire, at a constant speed completing one revolution every 1.9 s. The object has a mass of 1.75 kg. The radius of the circle is 2.3 m. (i) Draw a diagram indicating the direction of the following vectors: velocity, centripetal acceleration, centripetal force. [3 marks]...
Consider an object in uniform circular motion. A.) If the trajectory and the mass of the object are unchanged, but the centripetal force is doubled, is the object's speed multiplied by a factor of 1, square root of 2, 2, or 4? B.) If the mass of the object is halved and the radius of the circle quadrupled, while keeping the mass of the object the same, is the object's speed multiplied by a factor of1, square root of 2,...
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...

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...

In the uniform circular motion lab, the period for a complete cycle was measured for a mass spun at a constant speed about a fixed radius and with a constant centripetal force fc. If the radius was increased in increments while the force and mass remained constant, the period of a complete cycle is expected to? A. Increase B. Remain the same C. Decrease
