MOTION IN A
STRAIGHT LINE
Class-11th
, Mechanics
Mechanics is the branch of physics that deals with the study of motion of objects,
the forces responsible for the motion, and the conditions of bodies at resthysics
that deals with the motion of objects.
Mechanics is Divided into two parts:
1. Kinematics: Focuses on motion without worrying about the forces
causing it. Concerned with how objects move, not why they move.
2. Dynamics: Studies motion along with the causes behind it (like
forces). Aims to explain why objects move in a certain way.
,Examples of motion studied in Kinematics:
Motion along a straight line (1D motion)
Motion in a plane (2D motion)
Circular motion
1-D Motion
Circular Motion
2-D Motion
, Rest and Motion
Rest: An object is said to be at rest if its position does
not change with respect to its surroundings (reference
point) over time.
Example: A book lying on a table is at rest with
respect to the table.
Motion: An object is said to be in motion if its position
changes with respect to its surroundings over time.
Example: A moving car changes its position with
respect to trees, buildings, etc.
