(b) Movement and Position

• Define the SUVAT values

  • S - Displacement
  • U - Initial Velocity
  • V - Final Velocity
  • A - Acceleration
  • T - Time
• A scalar quantity has magnitude only while a vector quantity has magnitude and direction
• In a distance-time graph, speed is equal to the gradient of the line and in a velocity-time graph, speed is equal to area under the line
• Speed is the rate at which an object moves, velocity is the rate at which an object moves in a specific direction
• Acceleration is the rate of change of velocity
• When acceleration is negative, it means that the object is slowing down
