Uniform motion can be described by a few simple equations. Motion that changes the orientation of a body is called rotation. Motion, in physics, change with time of the position or orientation of a body. The distance s covered by a body moving with velocity v during a time t is given by s = vt. In both cases all points in the body have the same velocity and the same acceleration. (4) Example of sewing machine – The swing machine has a wheel which rotates on an axle. Now, we will try to explain motion in two dimensions that is exactly called “projectile motion”. In the above figure, different locations of the object during its PROJECTILE MOTION We see one dimensional motion in previous topics. So, a bicycle moving on a straight road has two types of motion rotational motion as well as rectilinear motion. Classical mechanics is the branch of physics that studies motion. The study of classical mechanics is quite expansive and includes the study of motion at the nanoscale and microscopic level (protein folding, enzymes) macroscopic level, all the way to the motion of aviation crafts, planets and … Uniform motion is motion at a constant speed in a straight line. If the velocity is changing, either in direction or magnitude, it is called accelerated motion … We can have different types of projectile type. So, the wheel of a sewing machine shows rotational motion. Students will distinguish between and/or interpret the types of motion. Motion along a line or a curve is called translation. In this type of motion gravity is the only factor acting on our objects. Examples (i) Motion of a vehicle on a straight line. Only one position co-ordinate is required to describe the position of the particle in this motion. This type of motion is also called rectilinear or linear motion. For example, you throw the ball straight upward, or you kick a ball and give it a speed at an angle to the The motion of a body is said to be in one dimension or one –dimensional motion if it moves along a straight line in any direction.
