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).
