Answers
motion is the change in position of an object with respect to its surroundings in a given interval of time. motion is the change in position of an object with respect to its surroundings in a given interval of time. Vibratory motion : The motion of an object where the moving object undergoes change in shape or size. For example all the musical instruments produce vibratory motion. Even during breathing, when our chest expands or contracts, the motion is vibratory in nature as all the points on the chest do not move out equally.
Periodic motion : A repetitive motion which repeats itself after a fixed interval of time is called the periodic motion. For example The piston of a motor car engine running at a constant speed. The swinging pendulum of a wall clock, Heart of a resting person beating 72 times in a minute etc.
Uniform motion : When a body covers equal distances in equal intervals of time along a same straight line, the body is said to be describing uniform motion. For example a flying aeroplane in a particular direction at a constant speed, a train moving straight in a particular direction at a constant speed are describing uniform motion.
