Lesson 1: HORIZONTAL AND VERTICAL MOTIONS OF A PROJECTILE

• SPEED


  The rate at which someone or something is able to move or operate
• VELOCITY


  A quantity that designates how fast a point is moving and in what direction.
• ACCELERATION


  The rate of change of velocity and a vector quantity that is defined as the rate at which an object changes its velocity
• PROJECTILE MOTION


  A combination of uniform horizontal motion and free fall.
• TRAJECTORY


  The curved path travelled by a projectile.
• PARABOLIC PATH


  The path traced by an object accelerating only in the vertical direction while moving at constant horizontal velocity.
• PROJECTILE


  A body travelling in projectile motion.
• RANGE


  The horizontal distance travelled by a projectile.
• HEIGHT


  The vertical distance travelled by a projectile.
• GRAVITY


  The force by which a planet, or other body draws objects toward its center.
• UNIFORMLY ACCELERATED MOTION (UAM)


  A type of motion in which the velocity of an object changes by an equal amount in every equal time period.
• Horizontal Motion - X - component

  • Neglect air resistance
  • Constant horizontal velocity (VX)
  • Horizontal acceleration is 0
