Answers
Ans6) time of ascent is the time taken by particle to go up when thrown from ground.
Time of descent is the time taken by particle to reach ground from its topmost position.
Ans7) SCALAR: A quantity with magnitude only. Eg. Distanceand speed
VECTOR: A quantity with magnitude as well as direction. Eg. Displacement and velocity.
Ans11) Uniform circular motion is the circular path traced by the object with constant velocity.
Ans12)Retardation is a.vector quantity.
Ans15) TRAJECTORY:Path followed by object when throwed from ground at an angle.
