chapter two

Is vector quantity which has both direction and magnitude

The change in position of an object displacement is also a vector quantity

Is the length of the path between two points and is measured in meteres it is a quantity scaler

The distance travelled in unit time

The speed of an object at A given instant of time

Is the speed in a given direction

1. Uniform motion. : The object moving with constant speed travels equal distances in equal time

2. Non uniform motion. : The object moving in travels in different distance in equal time

1. Speeding up. : If an object covers more distance than before in each second

2. Slowing down. : If an object travels less distance than before in each second

1. According to the speed of objects

   uniform motion and non uniform motion

2. According to the path of object

   1. Linear motion

   2. Circular motion

   3. Periodical motion

   4. Projectal motion

   5. Elliptic motion
