## What is physics class 9th?

Physics is the study of energy and matter in space and time. It deals with how the fundamental constituents of the universe interact. Content for Class 9 Physics covers the concepts of Motion, Force and Laws of Motion, Gravitation, Work and Energy and Sound.

What is motion in physics class 9 short?

Motion is defined as the movement of an object from one place to another. When an object moves along a straight line, the motion is known as rectilinear motion. Distance, displacement, uniform motion, non-uniform motion, speed, acceleration and velocity are the terms that are used for explaining the motion.

What are the topics in motion class 9?

### Can a displacement be zero?

Displacement can be zero even when distance is not zero. Consider two points A and B such that AB = 5 m. When a car travels from A to B and then back from B to A, distance = 5+5 = 10 m. Displacement = Minimum distance between final(B) and initial position(B) = 0.

What is the S.I. unit of motion?

The SI unit of motion is meter per second (m/s) because motion is deined as change in position of object with respect to its surrounding in given interval of time.
