Acceleration

• Acceleration

  The rate of change in speed or velocity of an object
• Acceleration


  • Gives an idea of how quick an object speeds up or slows down
• When an object is said to be accelerating


  • Change of speed
  • Change of direction
  • Change of speed and direction or velocity
• Positive acceleration


  Increase in speed or velocity
• Deceleration


  Decrease in speed or velocity
• Average acceleration formula

  Average acceleration = Change in velocity / Time
• SI unit for acceleration

  Meter per second squared
• Acceleration does not always mean an increase in an object's speed or velocity
• Acceleration


  refers to the rate of changchange in speed or velocity of an object
• Acceleration


  How quick an object speeds up or slows down
• The SI unit for acceleration is meters per second squared (m/s2).
• An example of acceleration is when a car starts from rest, it will have zero initial velocity but as soon as the engine starts, its velocity increases rapidly until it reaches its maximum speed.
• To calculate average acceleration, divide the total distance traveled by the time taken.
• Acceleration is measured by how much distance an object travels in a given time interval.
• If an object has no change in its velocity, it will have zero acceleration.
