Motion in a Straight Line
Class 11 · Motion in a Straight Line
Acceleration–Time Graph
Three-phase step function — area under a-t gives Δv.
Key Notes
01
a-t graph slope = jerk (da/dt). Area under a-t = change in velocity.
02
A step function in a-t means acceleration jumps suddenly between phases.
03
If a = 0, velocity is constant; if a is constant, velocity changes linearly.
Formulas
Change in v
Area under a-t gives velocity change.
Important Points
Impulse = ∫F dt = m·Δv — directly related to area under a-t (times mass).
