• Speed is defined as how far an object moves in a given time interval
• Average Speed:

  • Represents the speed of the object throughout its travel
• What quantity? Speed - Scalar Quantity
• Formula of Speed: Speed = Distance/Time
• Distance = Distance 1 + Distance 2 + Distance 3
• Velocity is Speed with direction
• Velocity = Displacement/Time the formula
• Distance refers to the length of the entire path that the object travelled
• Scalar - specified by magnitude(number) alone
• Displacement - The shortest distance between the objects two positions
• Velocity - how fast is an object moving and to which direction
• Reference point - Starting point
• Motion - A continuous change in position with respect to a reference point
• SI - System International Unit
• Speed describes the how fast or slow an object is
• Speed


  Is also which the location changes
• Constant Motion/Constant Speed

  If an object does not increase nor decrease it's speed then it's constant
• Instantaneous speed

  Measures how fast or slow an object moves in a particular time
• To get the distance, get the sum of all the magnitude of the object in motion
• To get the displacement, get the sum with the same direction then subtract with the opposite direction and copy the direction with the bigger magnitude
• Velocity - Vector Quantity
