    Frequently Asked Questions

    Motion is the change in position of an object with respect to time and a reference point.

    An object is said to be at rest if it does not change its position with respect to its surroundings.

    Distance is the total path length covered by an object during motion.

    Displacement is the shortest straight-line distance between the initial and final positions of an object.

    The SI unit for both distance and displacement is metre (m).

    Speed is the distance covered by an object per unit time.

    Speed = Distance / Time.

    Average speed is the total distance traveled divided by total time taken.

    Velocity is the rate of change of displacement with respect to time.

    The SI unit for both is metre per second (m/s).

    Motion in which an object travels equal distances in equal intervals of time is uniform motion.

    Motion in which an object covers unequal distances in equal intervals of time is non-uniform motion.

    Acceleration is the rate of change of velocity with respect to time.

    a = (v - u) / t, where v is final velocity, u is initial velocity, and t is time.

    Metre per second squared (m/s²).
