Short tricks for speed

  • The frame of reference, motion in a straight line, speed and velocity focus drill

    Solve 15 mixed MCQs for The frame of reference, motion in a straight line, speed and velocity, review every explanation, and note formulas you hesitated on.

  • Dimensional check first

    Before solving, verify each term has consistent SI dimensions — eliminates wrong options quickly in JEE MCQs.

  • Limiting cases

    Substitute extreme values (t→0, m→∞, θ→0) to sanity-check your final expression.

Q Type your question- 65kmh−1.65 k m h^{-1} . When they reach the crossroad, one of the cars turns towards town QQ whereas the other continues forward towards town RR. Both continue to move with the same speed of 65kmh−165 k m h^{-1} Which of the following options is correct for given statements? (i) Both cars have the same velocities even if the car turns towards town QQ (ii) Two bodies have same velocities if they are moving with same speed in different directions.
