Answer:

See Explanation.

Explanation:

  1. Student are always confused in velocity and speed.
  2. Mostly students assume velocity as scalar quantity not as vector quantity.
  3. If someone states that a object has velocity #-5 m/s# has significance but; if someone states that a object has speed #-5 m/s# does not posses significance. Students cannot understand that.
  4. Students cannot differentiate between speed and velocity.
  5. While applying the equations,
    #v=u+at#
    #v^2=u^2+2as#
    Students generally do not check whether velocity is zero at any time or not.

  6. Student are unknown that speed is modulus of velocity.
    Speed = IVelocityI

  7. Student may get wrong with the basic of the 2-D motion.
