Kinematics

1. Basics

   • Acceleration = V-U/t
   • Speed
     • average speed = distance/time
       • The total distance covered over a certain time interval
     • Instantaneous
       • The speed of an object at a particular instant
   • Displacement
     • Displacement is the shortest distance from the initial point to the final point; Thus, it is the length of an imaginary straight path
   • Velocity
     • The speed of an object in a particular direction
     • Accleration
       • The rate at which an objects velocity changes

2. Graphs

   • Displacement-time
     • Gradient = Velocity
     • Curved = Acceleration
       • Tangent = Instantaneous velocity
   • Velocity-time
     • Gradient = acceleration
