Which of the following has unit m/s²?

The correct answer is Acceleration.

Key Points

• Acceleration
  • The rate at which an object's velocity with respect to time changes is referred to as acceleration.
  • A vector quantity is an acceleration (has magnitude and direction both).
  • LT-2 or meter per second square(m/s2) is the unit of acceleration.

Additional Information

• Speed 
  • A scalar quantity, speed is defined as the magnitude of the rate at which an object's position changes over time.
  • The meter per second (m/s) or LT-1 unit of speed.
• Velocity
  • The pace at which an object's position changes in relation to a frame of reference is known as its velocity, which is a time-dependent quantity.
  • A description of an object's speed and direction of motion is what is meant by its velocity.
  • The quantity is a vector.
  • The meter per second (m/s) or LT-1 unit of velocity.
• Distance
  • The International System of Units defines a meter as the distance unit. It's interesting to note that many other derived units or quantities, such as volume, area, acceleration, and speed, may be constructed using this as the basic unit and a few formulae.
  • The meter(m) is the SI unit of length.
