Circular Motion Physics Classroom Answers


For an object moving in uniform circular motion, the velocity vector is directed a. radially inwards towards the center of the circle b. radially outwards away from the center of the circle on the direction of the tangent line drawn to the circle at the object’s location Use your average speed equation to determine the speed of ….



CIRCULAR MOTION WORKSHEET T = time/rev v = 2πr/T ac = v 2/r F c =m* … It takes a 900. kg racing car 12.3 s to travel at a uniform speed around a circular racetrack of radius 90.0 m. What is the centripetal force acting on the car, and which force provides it? 9. A 2.0 kg object is tied to the end of a cord and whirled in a horizontal circle of radius 4.0 m completing 2 revolutions in 6 …

Physics Circular Motion Solutions Evergreen State College


Physics Circular Motion Solutions Part I 1. If the radius of the path of a body in uniform circular motion is doubled and the speed is kept the same the force needed must be (a) half as great as before. (b) the same as before. (c) twice as large as before. (d) four times the size as before. Answer (a). Since speed is constant not frequency. 2.



UNIFORM MOTION PROBLEMS 1. Two trains start from the same station and run in opposite directions. One runs at an average rate of 40 miles per hour, and the other at 65 miles per hour. In how many hours will they be 315 miles apart? First Train Starting point Second train 40 mph x hours 65 mph x hours distance = rate x time distance = rate x time d = 40x d = 65x _____40x + 65x = …

Lecture 6 Circular Motion School Of Physics


uniform circular motion – tangential speed is constant. Is the object accelerating? Velocity is a vector ∴ changing direction ⇒ acceleration ⇒ net force 7. The change in velocity Δv = v 2 – v 1 and Δv points towards the centre of the circle Angle between velocity vectors is θ so Δv = vθ and so a = ∆v ∆t = vθ rθ/v = v2 r KJF §3.8 8. Acceleration points towards centre …

Uniform Circular Motion Problems With Answers


Solution: (a) The child has a circular motion with a centripetal acceleration as a_c=v^2/r ac = v2/r where v v is the constant speed of the revolving object. Therefore, a_c=frac 3^2 3=3quad
m frac m s^2 ac = 332 = 3 s2m (b) …

Chapter 10 Uniform Circular Motion


Uniform Circular Motion (Cont.) The question of an outward . outward force can be resolved by asking what happens when the string breaks! When central force is removed, ball continues in straight line. v. Ball moves tangent to path, NOT . NOT outward as might be expected. Centripetal force . Centripetal force is needed to change direction. Examples of Centripetal Force • • Car …
