Day-17 of Physics preparation *Force and Motion* Relative Velocity As we know , Rest and Motion are relative to each other *To find Relative velocity:* 1)Use: Vr=V1+V2 If two bodies are moving opposite to each other 2)Use: Vr=V1-V2 If two bodies are moving in same directions *Summary* • When Opposity(+) •When Same(-)
