See Explanation.
Explanation:
- Student are always confused in velocity and speed.
- Mostly students assume velocity as scalar quantity not as vector quantity.
- If someone states that a object has velocity
−5ms has significance but; if someone states that a object has speed−5ms does not posses significance. Students cannot understand that. - Students cannot differentiate between speed and velocity.
-
While applying the equations,
v=u+at
v2=u2+2as
Students generally do not check whether velocity is zero at any time or not. -
Student are unknown that speed is modulus of velocity.
Speed = IVelocityI -
Student may get wrong with the basic of the 2-D motion.
