2 study sections · pause after each one and recall the key ideaReal problems chain several stages together — thrown up, falling, bouncing.
Key points- Split the motion into stages and treat each with its own vi, vf and Δt.
- The final velocity of one stage becomes the initial velocity of the next.
- A bounce reverses the direction of velocity and usually reduces its magnitude.
- Total time is the sum of the stage times.
- Stage — a portion of motion with consistent conditions.
EXAM TIP
sketch the whole journey and label each stage before calculating — it stops you mixing values between stages.
