Rectilinear acceleration: WAEC Physics Past Questions and Answers
What the WAEC syllabus covers in Rectilinear acceleration
Our summary: How velocity changes with time in a straight line, with graphs and the equations of motion.
- Concept of acceleration/deceleration as increase/decrease in velocity with time (Unit of acceleration as m s⁻².)
- Uniform/non-uniform acceleration (Ticker-timer or similar devices should be used to determine acceleration. Definition of acceleration as $\Delta v / \Delta t$.)
- Velocity-time graph (Determination of acceleration and displacement from velocity-time graph.)
- Equations of motion with constant acceleration; motion under gravity as a special case (Use of equations to solve numerical problems.)
