What are some common mistakes students make with velocity?
- 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
#-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.
- Students cannot differentiate between speed and velocity.
While applying the equations,
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.
