FREE FALL AND PROJECTILE MOTION

• The process of moving faster.


  ACCELERATION
• The reduction in speed or rate.

  DECELERATION
• "How fast an object is moving"


  SPEED
• The speed of something in a given direction.

  VELOCITY
• The universal force of attraction acting between all matter.

  GRAVITY
• Strength or energy as an attribute of physical action or movement.

  FORCE
• The action or process of moving or being moved.

  MOTION
• An object is moving in a straight line, either forwards or backwards, up or down, left or right.

  MOTION ON ONE DIMENTION
• An object moving under the influence of gravitational force only.


  FREE FALL MOTION
• Galileo Galilei did an extensive study on bodies in motion and found out that an object in free fall goes down at a uniformly accelerated motion.
• According to the study of Galileo, the object becomes faster by about 10 m/s whatever the size or weight of the object is.
• Acceleration due to gravity -- Every second that an object falls, the velocity increases by 9.8 m/s².
• Vf = Vi + at

  FORMULA FOR FINAL VELOCITY
• d = Vi t + ½ at²

  FORMULA FOR DISTANCE
• An object undergoing projectile motion.

  PROJECTILE
• The arc or curve-like motion path undergone by the projectile.

  TRAJECTORY
• Motion that takes place in two different directions (or coordinates) at the same time.

  TWO DIMENTIONAL MOTION
• An object moves along a curved path under the influence of gravity.

  PROJECTILE MOTION
• The duration while the projectile is in the trajectory.

  TIME OF FLIGHT
• The maximum horizontal distance travelled by projectile.

  RANGE
• The maximum vertical displacement travelled by the projectile in its trajectory.

  MAXIMUM HEIGHT
• HORIZONTAL COMPONENT; Vx = Vi cos Ø : VERTICAL COMPONENT; Vy = Vi sin Ø
• Dy(max) = 𝐕𝐲² / 𝟐𝐠

  MAXIMUM HEIGHT
• Tup = 𝐕𝐲 / g

  TIME TO RISE
• Ttotal = 2Tup


  TOTAL TIME
• Dx = 𝐕𝐲𝟐 𝐬𝐢𝐧 𝟐Ø / g
