MOTION IN STRAIGHT LINE Chapter-03 Topic- Frame of Reference & Point Object PART-01, XI/NEET.
A frame of reference is a coordinate system used to describe an object's motion, while a point object is a simplified model of an object with no size. To describe an object moving in a straight line within a frame of reference, we use a single axis (like a number line) to measure its position, which changes with time. The object is considered in motion relative to the frame if its position changes; for example, a person on a bus is still relative to the other passengers but moving relative to a person on the
Motion in a Straight Line Class 11.

For a quick recap: A frame of reference is a coordinate system or a set of axes used to measure the position and motion objects. It's the perspective from wh...

In which of the following examples of motion, can the body be considered approximately a point object:A. A railway carriage moving without jerks between two stations.B. A monkey sitting on top of a man cycling smoothly on a circular track.C. A spinning cricket ball that turns sharply on hitting the ground.D. A tumbling beaker that has slipped off the edge of a table.

Hint: A point object is considered a small object or a dot object; it is considered a point object so as to simplify the calculations. An object.

Frame of reference
Definition:
A set of coordinates and a clock used to measure position and time. The description of motion depends on the chosen frame. 

Types:
Inertial Frame: A frame that is not accelerating; it is either at rest or moving with a constant velocity. Newton's laws apply directly in these frames. 

Non-Inertial Frame: An accelerating or rotating frame. Fictitious forces must be introduced to apply Newton's laws in these frames. 
Examples:
The ground is often used as a reference frame, and so are a moving car or a rocket. ĺ

A frame of reference which is at rest or which is moving with a uniform velocity along a straight line is called an inertial frame of reference.

Inertial Frame of Reference. An inertial frame is either stationary or moves at a constant velocity. Newton's laws of motion apply directly in these

Point object motion in a straight line

Definition:

A simplified model of an object with mass but no size, used to analyze motion along a single axis (one-dimensional motion). 

Description:

Motion is described by the change in position along this single axis over time. 

Key concepts:
Displacement: The straight-line distance between an object's initial and final positions. 
Velocity: The rate at which displacement changes over time, which is displacement divided by time
v=Δx/Δtv equals delta x / delta t
𝑣=Δ𝑥/Δ𝑡
Speed: The magnitude of the velocity. 

Example:
Describing a car moving along a straight road uses a number line where the car's position is its coordinate, and its velocity is how fast it moves along
