If it takes a centripetal acceleration of 3m/s2 for a car to go ar un a corner at 13 m/s, what is the W e then discuss motion of an object in a plane. Circular Motion When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Motion of the earth around the sun is an example of uniform circular motion. The resultant is the vector sum of two or more vectors. The curved motion is maintained so long as this net force provides the centripetal force requisite to the motion. u = the initial vertical velocity, usin ms-1). Solved problems in Newton’s laws of motion – Newton’s second law of motion 1.
