Questions and Answers

What role does force play in the motion of an object?

  • It is solely responsible for keeping objects at rest.
  • It can cause an object to change its velocity if not counterbalanced. (correct)
  • It has no effect if the object is moving at a constant speed.
  • It can only maintain an object's current velocity.
  • How is force mathematically characterized?

  • As an unmeasurable concept in physics.
  • As a scalar quantity with magnitude only.
  • As a quantity that describes only the direction of movement.
  • As a vector quantity with both magnitude and direction. (correct)
  • Which of the following statements about force is true?

  • Force cannot change an object's velocity.
  • Force encompasses both pushing and pulling influences. (correct)
  • Force is unrelated to the concept of velocity.
  • Only pushing forces are considered in physics.

    Study Notes

    Force Definition

    • Force is an influence that changes an object's velocity if not opposed by other forces.
    • Force precisely defines everyday ideas of pushing and pulling.
    • Force is a vector quantity, meaning both magnitude (strength) and direction are crucial.
