Mechanics

• Average speed-


  Total distance/total time
• Average velocity-


  Displacement/Total time
• Average acceleration-


  Change in velocity/total time
• Connected particles-


  When in equilibrium, tension between the 2 particles is equal, particles can be treated as one by just combining all forces as the tension cancels out
• Equations of motion- Newton's second law


  F=ma
• Measures ladder-


  Differentiate down, integrate up

  Displacement

  Velocity
