2.0 Circular Motion An object moves in a straight line if the net force
... An object moves in a straight line if the net force on it acts in the direction of motion or is zero. If the net force acts at an angle to the direction of motion or is zero. If the net force acts at an angle to the direction of motion at any moment, the object moves in curved paths. An object that ...
