Motion in a Straight Line
Class 11 · Motion in a Straight Line
Uniform Acceleration
Ball with initial velocity and constant acceleration — live v and a arrows.
Key Notes
01
Uniform acceleration: a is constant in magnitude and direction.
02
Three kinematic equations: v = v₀ + at, x = v₀t + ½at², v² = v₀² + 2ax.
03
The v-t graph is a straight line; x-t is a parabola.
Formulas
First equation
Velocity from time.
Second equation
Position from time.
Third equation
Velocity from position (time-independent).
Important Points
Use the third equation when time is not asked — saves algebra.
