(b) rectilinear motion (c) curvilinear motion
Answers
Rectilinear Motion: Motion of the object in straight line path is called rectilinear motion. For example : Motion of train on track, motion of ants in a straight path,motion of freely falling stone from top of the building towards the ground.
Circular Motion: Motion of object in a circular path is called circular motion. For example: Children playing ringa ringa roses or moving in a circle, motion of Earth around the Sun.
Periodic Motion : Motion of a object which repeats itself after a certain period of time is called periodic motion. For example : Motion of Earth around the sun is periodic as well as circular as it repeats it motion after time of 365 days. Motion of simple pendulum is periodic.Motion of minute and second hand in a watch is periodic.
EXAMPLES OF DIFFERENT TYPES OF MOTION - EXAMPLE
Sr.No. Types of Motion Examples
1 Rectilinear a)March past by the soldiers in straight line. b)Motion of falling objects from certain height
2 Circular a) Motion of satellites around planets. b) Motion of car turning to a curved track
3 Rotational a) Motion of giant wheel b) Motion of wheels of moving vehicle
4 Periodic a) Motion of simple pendulum b) Motion
A bus travels along a straight path and also some times along curved path its motion is rectilinear motion or simply linear motion. A bus moves along straight line so we can we one dimensional motion's equation to calculate any dimension regarding its motion.
