FORCES (1)

• Displacement


  The gap between the initial position & the final position of an object
• Velocity


  The speed at which something moves in one direction
• Acceleration


  The time rate of change of the velocity of an object
• Force


  Push & pull applied to an object<|>An influence that changes the motion of an object<|>The primary cause of all the motion & movements we see every day<|>Force is present even if an object isn't moving
• Magnitude


  Refers to how strong the force is<|>Is expressed in various ways
• How magnitude is expressed

  • Newton (Meter-Kilogram-Seconds System (MKS))
  • Dyne (Centimeter-Gram-Second (CGS))
  • Pound (Foot-Pound-Second System (FPS))
• Direction


  Refers to the points to where the object goes
• Point of application


  Location where the force is applied
• Line of action


  Straight line passing through the point of application<|>Is parallel to the direction of the force
