dont attempt to pass unless on a double highway
No. No, but you should check your local driving laws just in case.
Yes, and with all cars. It is based on rotational steering.
A train operator should blow their horn when approaching crossings where cars or pedestrians may be. They should also always have their lights on.
The wreckage will not move in any particular direction and will remain stationary, as the cars have equal but opposite momenta which cancel each other out.
It means that you are about to be lapped and need to let the faster car overtake. If a driver fails to let the car pass after three blue flags he is likely to be penalized. They are also shown at the end of the pitlane if a car is approaching on the track, so that the driver exiting the pits knows to be careful.
Generally it means that the cars on the other side of the line will be travelling in the opposite direction as you are. A white line means that the traffic is facing the same direction as you, or that there is no travel across the line (shoulder).
Force only takes place in the direction of the motion. It cannot be any other way. It could be argued that the action of a cars tyres on the road applies to your question. The car moves forward while the tyres push the earth in the opposite direction. However the tyres are the motion supplying the force and not the car moving in the opposite direction..
No, because velocity includes direction as well as speed.In order for the velocities to be the same, they would have to go the same speed in the same direction.
The amount of damage relates to the relative motion of the two cars. So, if the cars are moving in opposite directions when they collide, the relative motion and the resulting damage is greater; if they are moving in the same direction, then the relative motion and the resulting damage is less. A motionless car is intermediate between a car moving in the same direction and a car moving in an opposite direction.
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
