Linear Motion - Coggle Diagram
Linear Motion
Displacement
Definition: Change in position between initial and final points.
SI unit: meters (m)
Formula: comparing final vs initial
Graph: Represented by position time graphs. Steeper slope indicates faster movement.
Velocity
Definition: Rate of change of displacement.
SI Unit: Meters per second (m/s)
Formula
v = change of speed / change of time (Average velocity)
v = u + at (velocity with constant acceleration)
Graphs
Area under the graph: Represents total displacement (since v = ds/dt)
Gradient:
Represents acceleration (since a = dv/dt).
acceleration
Definition: Rate of change of velocity.
SI Unit: Meters per second squared (m/s²)
Formulae
a = Δv / Δt
(average acceleration)
a = (v - u) / t
(acceleration with constant initial and final velocities)
