In a uniform circular motion, a body has a:
  • Constant speed
  • Constant velocity
  • Zero velocity
  • zero speed
The area enclosed by velocity-time graph and the time axis will be equal to the magnitude of
  • distance
  • acceleration
  • speed
  • displacement
If a train is traveling due north and its brakes are applied, it will have?
  • Acceleration towards north.
  • Acceleration towards south.
  • zero acceleration.
  • Acceleration towards east.
The equations of motion can be derived by using:
  • Velocity - time graph for uniform acceleration
  • Velocity - time graph for non-uniform acceleration
  • Distance - time graph
  • Displacement time graph
An athlete moves along on a circular track with a constant speed. This is an example of:
  • Linear motion
  • Translatory motion
  • Uniform circular motion
  • Irregular motion
The following position-time graph of an object shows that the body
  • No such inference can be made from the graph.
  • Has non-uniform motion.
  • Has uniform motion.
  • Is at rest.
The speed of the body in the time interval 14 to 18 seconds is
  • 20 m/s
  • 0
  • 12 m/s
  • 10 m/s
The velocity time graph of two bodies A and B traveling along the +x direction are given in the figure. Which body has a greater acceleration?
  • Body A has a greater acceleration
  • Body B has a greater acceleration
  • Both A and B have same acceleration
  • Acceleration cannot be predicted from the given graph
Speed of 90 km/h when expressed in m/s is
  • 250
  • 25
  • 90000
  • 2.5
The S.I. unit of acceleration is:
  • ms
  • ms2
  • ms-2
  • m
0 h : 0 m : 1 s
