  • A car starting from rest accelerates uniformly to acquire a speed 20 km/h in 30 min. The distance traveled by car in this time interval will be?
    5km
  • Define One Dimension Motion
    When a body moves along a straight line path, its motion is said to be one dimension motion.
  • A body starts from the rest and acquires a velocity of 10m/s in 2s. Find the acceleration.
    5m/s
  • What is the S.I. unit of speed?
    m/s
  • A train moving with a velocity of 20m/s is brought to rest by applying brakes in 5s. Calculate the retardation.
    4m/s^2
  • S.I. unit of retardation.
    ms^-2
  • Can displacement be zero even if distance is not zero?
    Yes
  • One dimension motion is also called as _______________
    Rectilinear motion
  • Momentum is a scalar quantity. (True/False)
    False
  • Arrange the following speeds in increasing order: 10 ms^-1, 1km min^-1, 18 km h^-1
    The increasing order is 18 km h^-1, 10 ms^-1, 1 km min^-1
