MOTION

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
