It is possible for a free body to make rotational motion with the effect of one only force?
Rotational motion is the movement of an object around an axis or fixed point. It is different from linear motion because the object moves in a circular or curved path instead of a straight line.
Yes, one force can cause rotational motion as long as it acts on an object at a distance from its center of mass, creating a torque or rotational force. This torque causes the object to rotate around its center of mass.
The direction of the force affects the direction of the resulting rotational motion. For example, if the force is applied perpendicular to the axis of rotation, it will cause the object to rotate in a plane perpendicular to the force. If the force is applied at an angle, it will cause the object to rotate in a tilted plane.
Yes, multiple forces acting on an object can cause rotational motion. The total torque on the object is the sum of all the individual torques from each force. As long as the net torque is not zero, the object will experience rotational motion.
Rotational motion is measured using a unit called radians, which is a measure of the angle of rotation. One radian is equal to the angle subtended by an arc of length equal to the radius of the circle. The number of radians an object rotates is directly proportional to the distance traveled along the circular path.
