![]() Considering the initial velocity of 10 m/s at which the ball is initially rolling on a flat table. The x-axis will define the horizontal direction, and the y-axis will determine the vertical direction. The figure below shows Translational Motion examples or the simple example of projectile motion: a ball rolling off a table. ![]() To fix the position of the object in the two dimensions, we need two coordinates. In two or three dimensions, the motion of an object is complicated. This is expressed in the form of an equation that relates distance x, to time t. The motion of the object will be known when the position of the object at a particular time is known. With an appropriate sign, the distance x defines the position of the object. In the following figure, a position occupied by the body at any time t is represented. When the movement of a body is along a straight line, it is known as the rectilinear motion. A typical example of Translatory motion is the motion of a bullet fired from a gun. Translational Motion definition– The motion with the help of which a body moves from one point in space to another is known as the Translational Motion. The two types of motion that a Rigid Body undergoes are: What has come after Quantum Mechanism? The foundation of it is laid by the Rigid Body dynamics. To have a better understanding of the world around us, we need to explore and understand different kinds of problems. What kind of motion could a Rigid Body have? This gave a new outlook, which meant that there could be two different types of Rigid Body motion. In a practical world, the deformation of wheel and steel rods is considered to be negligible and is considered as rigid. Motions like the potter wheel, rotation of the fan, etc. ![]() To solve a range of problems that could not be explained with classical Physics, the Rigid Body and Rigid Body dynamics concept was developed. For example, a bridge will not change shape under the weight of a single person, but it might change shape under the weight of a truck, even though the change will be small.Īs in real life, no substance is rigid there is another concept regarding the body known as the resistant body, which is utilized in finding solutions for engineering problems. Or it can be said that a body that does not change shape under the influence of forces is known as a Rigid Body.īut practically there will be some forces under which the body will change shape. When an external force acts on a body and the distance between the two points on the body doesn’t change, then the body is known as a Rigid Body.
