Motion in One Dimension

🌈 Rainbow Mindmap: Motion in One Dimension

Rectilinear Motion

Motion along a straight line path. The simplest type of one-dimensional motion where position changes linearly with time.

Example: A car moving straight on a highway or a train on straight tracks

Oscillatory Motion

Repetitive back-and-forth motion about a central position. Characterized by periodic motion like a pendulum or spring.

Example: Swing of a pendulum clock or a mass on a spring

Position-Time Graphs

Graphical representation showing how an object's position changes over time. Slope indicates velocity (steepness = speed).

Straight line = constant velocity, Curved line = acceleration

Velocity-Time Graphs

Shows velocity variation with time. Slope gives acceleration, area under curve gives displacement. Horizontal line means constant velocity.

Positive slope = speeding up, Negative slope = slowing down

Uniform Motion

Motion with constant velocity (zero acceleration). Equal displacements in equal time intervals. Position-time graph is a straight line.

Example: Car moving at constant 60 km/h on straight road

Accelerated Motion

Motion with non-zero acceleration. Velocity changes with time - can be uniform or non-uniform acceleration. Free fall is a common example.

Example: Object falling under gravity (9.8 m/s² downward)

Kinematic Equations

Mathematical equations that describe motion: v = u + at
s = ut + ½at²
v² = u² + 2as
(u=initial, v=final velocity)

These equations only work for constant acceleration scenarios
