Question

Motion chapter explanation of class 9​

Answer 1

Answer:

hey Mate here is your answer....

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.physics, motion is the change in the position of object over time.

Motion is mathematically described in terms of displacement,distance, velocity,acceleration, speed, and time.SPEED WITH DIRECTION

The velocity of an object can be uniform or variable.

It can be changed by changing the object's speed, direction of motion or both. When an object is moving along a straight line at a variable speed, we can express the magnitude of its rate of motion in terms of average velocity.

Hopefully it's helpful for you
