4th prelims

• a from of motion where an object moves in a curved path

  projectile motion
• an object undergoing projectile motion

  projectile
• the parabolic path taken by a projectile

  trajectory
• in x component, it neglects air resistance
• in x component, there is a horizontal velocity which represents?

  Vx
• horizontal acceleration is

  0
• we call the horizontal distance as the

  range (dx)
• the force acting upon this, is the force of

  gravity
• We call the vertical distance as the

  height (dy)
• Vertical velocity is not constant
• the vertical distance from the projectile to earth's surface

  height
• horizontal distance covered by the projectile

  range
• the orientation of a projectile to be thrown / projected

  angle
• As the projectile reaches the maximum height, it momentarily stops causing vertical velocity equal to zero
• As the angle of launch increases, the vertical displacement of the projectile will also increase.
• At the highest point, the vertical component of velocity is zero and the time to reach the maximum height is half of the total time of flight. 
• The product of mass of the object and its velocity.

  momentum
