作者:Deepthi Muthu

1. Types of motion
1.1. UNIFORM
1.1.1. equal distances in equal intervals of time
1.2. NON-UNIFORM
1.2.1. unequal distances in equal intervals of time
1.3. UNIFORM CIRCULAR
1.3.1. equal distances in equal intervals of time on a circular path
2. Rate of motion
2.1. 1km/hr=5/18 m/s ; 1 mile/hr=1.6 km/hr
2.2. Speed=Distance/Time
2.3. Velocity=Displacement/Time
2.4. Acceleration=Change in Velocity/Time taken
3. Change in position
3.1. DISTANCE
3.1.1. Actual Distance covered
3.1.2. Can be 0/+
3.1.3. Scalar Quantity
3.1.3.1. only has magnitude
3.1.4. Unit is m (metre)
3.1.5. 1 inch=2.54 cm
3.1.6. 1 foot=30 cm
3.2. DISPLACEMENT
3.2.1. Distance covered in a straight line
3.2.2. Can be 0/+/-
3.2.3. Vector Quantity
3.2.3.1. has both magnitude and direction
3.2.4. Unit is m (metre)
