Important points about velocity and acceleration

Here are important points about velocity and acceleration:

• Velocity:

  • Velocity is the rate of change of displacement. It describes both the speed and the direction of an object's motion.
  • It is a vector quantity, meaning it has both magnitude (speed) and direction.
  • The SI unit for velocity is meters per second ($\text{m/s}$).

• Acceleration:

  • Acceleration is the rate of change of velocity. It describes how quickly an object's velocity is changing.
  • It is also a vector quantity, meaning it has both magnitude and direction.
  • An object accelerates if its speed changes, its direction changes, or both.
  • The SI unit for acceleration is meters per second squared ($\text{m/s}^2$).
