A stone dropped from a height h takes 2 s to fall. Drop it from 2h. How long does it take now?

Every answer is computed before it reaches you.
What the free unit will cover

Physics and Measurement

  • Why every measurement needs a unit, and how SI units fit together.
  • Dimensions: checking a formula without solving it.
  • Errors and significant figures, the way JEE and NEET ask them.
  • The full practice mission, with spaced review.
  1. 1DecodeWhat is this?Acceleration in one picture and two lines.
  2. 2QuizCan I recognise it?Which graph shows constant acceleration?
  3. 3RecallCan I say it from memory?Write v² in terms of u, a and s.
  4. 4PredictDo I know what happens?Drop it from twice the height. How much longer does it fall?
  5. 5SolveCan I work it out?A car brakes from 72 km/h to rest in 4 s. How far does it go?
  6. 6ExamCan I do the real thing?Past JEE and NEET questions, with the year shown.
