Question

Which of the following best describes the net force acting on an object moving with uniform circular motion? Check all the apply

a. the net force acting on the object is away from the center of the motion and the acceleration of the object os toward the center of the motion

b. both net force acting on the object and the acceleration of the object are away from the center of the motion

c. the net force acting on the object is tangent to the circle in which the object is moving and the aacceleration of the object is toward the center of this circle

d. both the net force acting on the object and the acceleration of the object are toward the center of the circle in which the object is moving

e. the net force acting on the object is toward the center of the circle in which the object is moving and the acceleration of the object is tangent to the circle in which the object is moving

Answer 1

An object is moving with uniform circular motion,the velocity of the object remains constant in magnitude but direction of motion is tangent to the circle. The change in velocity is always directed towords center of circle.Acceleration is rate of change of velocity acts towords center of circle, resulting a constant net force (centripetal force acts towords the center of the circle. Therefore following option is true.

d. both the net force acting on the object and the acceleration of the object are toward the center of the circle in which the object is moving
