• Momentum


  • Refers to how difficult it is to stop motion
  • It is the inertia in motion
  • It is the measure of how difficult it is to stop a moving object
  • It utilizes the first law of motion, the Law of Inertia
• Speed


  Momentum
• Mass


  Momentum
• Factors affecting momentum


  • Mass (symbol: m | unit: kg)
  • Velocity (symbol: v | unit: m/s)
  • Scalar - no direction
  • Vector - with direction
• Momentum formula


  • P=mv
  • Symbol: P
  • Unit: kgm/s
• Impulse


  • The change of momentum of an object when the object is acted upon by a force for an interval of time
  • It utilizes the second law of motion, the Law of Acceleration
• Factors affecting impulse


  • Force (symbol: F | unit: kg.m/s^2 or N)
  • Time (symbol: t | unit: s)
  • Mass (symbol: m | unit: kg)
  • Acceleration (symbol: a | unit: m/s^2)
  • Final Velocity (symbol: vf | unit: m/s)
  • Initial Velocity (symbol: vi | unit: m/s)
• Impulse formula


  • I=Ft
  • Ft=mvf-vi
• The second law of motion states that the net force of an object is equal to the product of its mass and acceleration
• Acceleration is the rate at which the velocity of a body changes with the time and is expressed as a=vf-vi/t
• The combination of the general formula and the acceleration formula is Ft=mvf-vi
• The third law of motion states that for every action, there is an equal but opposite reaction
• When two bodies approach each other from two opposite directions without stopping, then these objects will collide
• The third law of motion states that the forces the objects exert on each other are equal in magnitude and opposite in direction
• Law of Conservation of Momentum


  In an isolated system, the momentum before the collision is equal to the momentum after the collision
• Types of collisions


  • Elastic Collision - after the collision, the two objects did not stick together. There are no deformations after the collision.
  • Inelastic Collision - after the collision, the two objects stick together
• Formula for Inelastic Collision


  • v'=v1'=v2'
  • m1v1+m2v2=v'(m1+m2)
