Eight Standard

Test your understanding of this lesson Force | Introduction:-

1)
State of motion is given by-
  • The magnitude of speed
  • The direction of motion
  • The magnitude and direction of speed both
  • None of above
2)
What should be applied to change the state of motion?
  • External force
  • Force and acceleration
  • Pull
  • Push
3)
How can we predict that force is applied?
  • State of motion changes randomly
  • State of motion changes or tries to change in the direction of applied force
  • The body maintains its state of motion
  • The body exhibit rectilinear uniform motion
4)
unit of force in SI system –
  • Pascal
  • Dyne
  • Newton
  • none of these
5)
If External force is not applied,then what will be the motion –
  • The motion wil be circular
  • The motion will be rectilinear
  • The motion will be non uniform
  • The body will retain its previous state of motion
