Motion — Supplement Learning Objectives
Summary
- Define acceleration as change in velocity per unit time; recall and use the equation a = Δv / Δt
- Determine from given data or the shape of a speed-time graph when an object is moving with: (a) constant acceleration (b) changing acceleration
- Calculate acceleration from the gradient of a speed-time graph
- Know that a deceleration is a negative acceleration and use this in calculations
- Describe the motion of objects falling in a uniform gravitational field with and without air/liquid resistance, including reference to terminal velocity
