Answers
Answer:
(1)Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).
(2)Representational state transfer is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of an Internet-scale distributed hypermedia system, such as the Web, should behave.
Answer:
I. 1) Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).
2) a body is said to be at rest, if it does not change its position with respect to its surrounding with time.
3) motion in which all points of a moving body move uniformly in the same line or direction.
4) Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
6) In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
5The motion of an object moving in a curved path is called curvilinear motion.
7) Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
8) A motion repeating itself is referred to as periodic or oscillatory motion.
9) The motion which does not repeat itself after a regular interval of time is called non-periodic motion.
10) Rolling is a type of motion that combines rotation and translation of that object with respect to a surface, such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as pure rolling.
11) Random motion - when an object in motion with no specific path and changes its motion suddenly.
12) When an object perform two or more types of motion at the same time, then the motion of the object is called as multiple motion.
