### Motion g7

1. 1. mstfdemirdag.com
2. 2.  An object is in motion if its place changes with respect to a fixed point which we call the reference point.
3. 3.  The distance of an object to a reference point in a stated direction gives the position of the object. Position is a vector quantity which has both direction and magnitude.
4. 4.  The change in position of an object is called displacement.
5. 5.  Distance traveled in unit time is called speed.
6. 6.  Average speed is calculated by dividing the total distance traveled by the total time taken.
7. 7.  When we talk about speed and direction, we use the term velocity.
8. 8.  If an object moves with constant speed its motion is called uniform motion.
9. 9.  Speeding Up: If an object covers more distance than pervious second its motion is called speeding up. Slowing Down: If an object covers less distance than pervious second its motion is called slowing down.
