Notes for ch8 science physics in english
Hello Aspirant,
Chapter 8 in Science Physics for Class 10 (NCERT) is typically Motion .
Here are key notes:
-
Motion : When an object changes its position with time.
-
Distance : Total path covered (scalar, no direction).
-
Displacement : Shortest path from start to end (vector, has direction).
-
Speed : How fast an object moves (distance/time).
-
Velocity : Speed with direction (displacement/time).
-
Acceleration : Change in velocity over time.
Types of Motion : Uniform (constant velocity) and Non-uniform (changing velocity).
Graphs : Distance-time graphs (slope = speed), Velocity-time graphs (slope = acceleration, area = displacement).
Equations of Motion : v=u+at, s=ut+1/2at2, v2=u2+2as. (where u=initial velocity, v=final velocity, a=acceleration, t=time, s=displacement).
