Car and truck approaching each other


Nothing is getting closer towards the other thing, so that means the car it's not in any way getting closer to the track that's why it's zero meters per second okay. So this case ladies and gentlemen this is where this is moving at 20 this is moving at 20 okay. 

So you now have a truck and a car okay, so they're approaching each other so now this is traveling at 20 this is traveling at 20 meters per second so this is the speed latest engine can you see. So when you compare the speed of the truck versus the speed of the speed of the car versus the speed of the truck it's more like this is moving at two times the speed because it's 20 ladies and gentlemen. 

Can you see, so for it to make a perfect sense let's say the truck is not moving, let's say the car is moving obviously at 20 meters per second okay so this is, this is what happens can you see ladies and gentlemen, so if it's only the car which is moving you can see is 20 meters per second. 

What if they are both moving at the same speed? Can you see ladies and gentlemen, so it's more like this is moving at 40 meters per second relative to the track. It's different from when this object is moving alone and not being compared to anything else okay very  much important ladies and gentlemen very much important.
