• Distance


  the actual length coverd by an object.

  It is a scalar quantity meaning it only has a numerical value.
• scalar


  magnitude
• vector


  mag -1 direction
• Displacement


  The straight line or short cut from the initial position to the final position with direction
• Speed


  How fast you are travelling
• Velocity


  The speed in a given direction
• Scalar quantities

  • Distance
  • Speed
• Vector quantities

  • Displacement
  • Velocity
• uniformly accelerated motionis 


  motion of an object where the acceleration is constant.
• projectile motion


  moves along a curved path under constant acceleration directed towards the center of the earth
• Trajectory


  the arc-curved like motion path undergone by a projectile
• Vertical motion


  the force acting upon this motion is the force called gravity.
• we call the vertical distance as height
• range


  horizontal distance covered by the projectile.
