An object is in motion when its distance from another object is changing.  WHAT IS POINT OF REFERENCE? It is a place or object used for comparison to determine if something is in motion. d=3 cm d=3 cm d = 7 cm  Distance (d) It is the total length of path travelled by an object from its initial position to its final position.  Displacement (Δ d) It refers to how far out of place an object is from its initial position. It is the object’s overall or net change in position. Points to Remember: In solving for the distance, get the sum of all the magnitude of the object in motion. In solving for the displacement, get the sum of the magnitude of the same directions. Then, subtract the magnitude of opposite directions and follow the direction of the bigger magnitude. Problem #1: A man moves from Point A to Point B then to Point C and finally to Point D. Find the distance and displacement travelled by the man. Problem #1: d = 50 m + 30 m + 50 m d = 130 m Δd = 30 m, North Problem #2: A car moves from Point A to Point B then to Point C as shown in the diagram. Find the distance and displacement travelled by the car. Problem #2: d = 800 m + 300 m Δd = 1100 m, to d = 1100 m the right Problem #3: A car travels from A to B and returns to its original position. 2000 m Problem #3: d = 4000 m 2000 m Δd = 0 m Problem #4: A Physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North. Problem #4: 4 meters East 2 meters South 4 meters West 2 meters North d=4m+2m+4m+2m d = 12 m Δd = 0 m  DISTANCE OR DISPLACEMENT?
