• PROJECTILE


  An object thrown or propelled with force, typically launched into the air and subject to the forces of gravity and air resistance. Examples include a thrown baseball, a launched rocket, or a fired bullet.
• TRAJECTORY

  The path followed by a projectile or object as it moves through space or air under the influence of external forces, such as gravity and air resistance. is typically depicted as a curve.
• GRAVITY


  The force that causes objects to fall toward the ground and is responsible for keeping celestial bodies like planets and moons in orbit around each other.
• ANGLE OF PROJECTION


  The angle at which a projectile is launched or projected relative to the horizontal plane. It significantly affects the trajectory and range of the projectile.
• VELOCITY


  A vector quantity that describes the rate and direction of motion of an object. It is the combination of speed (magnitude of motion) and direction.

  
• ACCELERATION


  The rate of change of velocity of an object over time. It can refer to an increase or decrease in speed or a change in direction.
• DISPLACEMENT


  A vector quantity that refers to the change in position of an object relative to a reference point or starting point.
• RANGE


  The horizontal distance covered by a projectile or object from its initial position to its final position.
• Impulse


  The change in momentum
• Impulse Momentum Theorem


  1. I = Ft

  2. Where, I - Impulse (N-s)

  3. F - Force (N)

  4. t - time (s)
• Inertia


  • An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
• Newton's Second Law of Motion Acceleration 


  • The larger the mass of the object, the greater the force will need to be to cause it to accelerate
• Mass


  A measure of the body's inertia, the resistance to acceleration when a net force is applied
• Force


  An influence that can change the motion of an object
• Acceleration


  The rate of change of the velocity of an object with respect to time
• Newton's Third Law of Motion Interaction


  • Every action, there is an equal and opposite reaction
• Collision


  Occurs when two or more bodies come in contact with each other. During a collision, the interacting bodies hit and exert a force on each other. In general, when two or more bodies collide, linear momentum is always conserved. The total kinetic energy may or may not be conserved depending on the type of collision.
• Perfectly inelastic - The bodies cling to each other after collision and move with a common velocity v. Kinetic energy (KE) is not conserved.
• Elastic - Bodies separate after collision.Kinetic energy is conserved.
• Inelastic - Bodies separate after collision.Kinetic energy (KE) is not conserved.
• Coefficient Of Restitution - An act of giving what is stolen or taken or loss.
• Kinetic energy is the energy that objects possess due to their motion.

  KE = 1/2mv^2

  m = mass (kg)

  v = velocity (m/s)

  KE = Kinetic energy (J)
• Impulse Momentum formula

  F🔼t = m🔼V
• Weather - mix of events or conditions that happens in our atmosphere over a period of hours or days
• Climate - refers to the average weather conditions in a place over many years.

  • Temperature
  • Humidity
  • Rainfall or precipitation
• Rainy Season

  June - November

  Dry Season

  December - May

  Cool Dry Season

  December - February

  Hot Dry Season

  March - May
• Latitude - the specific

  North to South grid positions on

  earth ranging from 0° at the equator to 90° at the poles
• Altitude - height of an area above sea level.

  • At higher elevations, there is less air.
  • The aip molecules are farther apart, thus making the air less dense.
  • Less dense air cannot absorb much eat, making air temperature decrease.
  • It allows the particles in the air to expand, which reduces the air pressure even further.
• Topography - refers to the natural features or arrangement of an area like land.
• Distance to oceans

  • Areas that are close to oceans and other large bodies of water tend to have more moderate climate changes between seasons.
• Ocean Currents

  • are caused by the wind, earthquakes and gravity. •that flow away from the equator carry warm water. • that flow from the currents away from the poles carry cold water. • that bring along cold water inland make the climate cold.
• Momentum - a mass in motion
• Linear momentum - object moving in a straight line
• Work - The product of force that produces a parallel displacement.
• Energy- Ability or capacity to do work.
• Potential Energy - Stored energy or not in motion
• Power - ability to do work in certain amount of time.
