If a body is involved in rectilinear motion, and if the motion is not consistent,... When an object falls freely due to gravity and if we ignore the effects of air resistance to a good approximation the object falls with a constant acceleration. Motion of earth around the sun. The acceleration felt by any object in uniform circular motion is given by a = . Example: Motion of the earth around the sun: Example: Motion of a body on vertical circle. Examples of Uniform Circular Motion There are innumerable examples of circular motion in nature. Practice Problems: Uniform Circular Motion Solutions. In that case, the object’s speed remains constant, hence “uniform”, while its direction is constantly changing, this is necessary to keep it moving in a circle. e.g. Therefore, the magnitude of centripetal force, Fc, is. An object with uniform circular motion travels in a circle with a constant speed. Its unit in the International System (S.I.) We can specify the instantaneous position of the object in terms of its polar coordinates and . The equations for the non-uniform circular motion, also known as uniformly accelerated circular motion are the following: : Angular velocity of the body at the considered moment and at the initial moment respectively. Speed and acceleration of an object moving in a circle of constant radius. For a small amplitude oscillation, a pendulum is a simple hamonic oscillator.

(iv) An athlete running on a circular track with constant speed. Average speed = 22/10 = 2.2 m/s Thus: v = = = = 3076 m/s. One important element that makes circular motion possible is an inward force; this is also called the centripetal force. The ball makes 2.00 revolutions in a second. Non uniform: here when the direction or the rate of change of speed changes. Examples of uniform rectilinear motion The uniform rectilinear motion (MRU) It is a movement that is carried out on a straight line, at constant speed (with constant magnitude and direction). If the time distance graph is a straight line the motion is said to be uniform motion. (a) Derive the equation of motion v = u +at, using graphical method. For objects in uniform circular motion, the net force and acceleration is towards the center of the circle. Under conditions of centripetal motion, a body with mass m traveling a circular path of radius r around a point will have a linear velocity tangent to the circle. The motion in which the body moves with constant speed and has zero acceleration is called Uniform motion. The simplest example of accelerated motion in a straight line occurs when the acceleration is constant (uniform). In 60 seconds it covers a distance of 1800 meters. The movement of an object in a circle with a constant or uniform speed. Thus, for the uniform motion, the speed of the moving body remains constant.
