A good example of shm is an object with mass m attached to a spring on a frictionless surface, as shown in (figure). In simple harmonic motion, the acceleration of the system, and therefore the net force, is proportional to the displacement and acts in the opposite direction of the displacement. The acceleration due to gravity on this planet is (a) (b) (c) (d) 9.8 m/s2 4.9 m/s2 19.6 m/s2 2.45 m/s2 can not be determined from the given data.
Dynamics is the study of how forces affect the motion of objects, whereas kinematics simply describes the way objects move. Angular velocity gives the rate at which the object is turning through the curve, in units of rad/s. When torque is positive, the angular speed must be positive. Angular acceleration of a propeller shows a graph of the angular velocity of a propeller on an aircraft as a function of time.
