Answers
Answer:
REST IS PRESENT IN ONE PLACE AND THERE IS NO MOVEMENT
MOTION IS MOVE ANY OTHER SIDE
Answer:
Hey buddy that's your answer .
Answer: A body is said to be at rest if its position does not change with respect to its surroundings. Whereas, when the position of a body changes with respect to its surroundings, it is said to be in motion.
Circular when the body moves around some other body. Rotatory motion is when a body spins around its centre of gravity or its own axis. Circular motion is due to centripetal force, while rotatory motion involves torque . The circular motion revolves around another body, while rotatory motion, is in its own axis.
Distance travelled is a scalar quantity while displacement is a vector quantity. When a body continuously moves in the same straight line and in the same direction then displacement will be equal to the distance travelled.
The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
Linear motion is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. ... Random Motion is a motion in which an object didn't go in a straight manner, the object move in a zig zag manner.
Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
