In accident reconstructions, head on collisions where equal mass vehicles come to a stop on impact are virtually nonexistent. Physics says the much lighter vehicle should be carried backwards by the heavier one, but it never happens, the smaller car will go underneath or off to the side

Not sure. All I know is that there wouldn't be a tiny car for very long... ^_^

What happens if two molecules traveling at the same speed collide head on?

If two molecules traveling at the same speed collide head on, they will exchange energy and momentum. This can result in the molecules bouncing off each other in opposite directions or sticking together to form a new molecule. The outcome depends on the specific properties and interactions of the molecules involved.


How is crash speed determined when two vehicles are moving in the same direction?

The difference between the two speeds. So if one car is traveling at 60mph and the other is 70mph, it would be a 10mph difference since they are traveling in the same direction. Now, if they were colliding head on, it would be 130mph total speed.Also, 2 cars traveling at exactly the same speed and direction (assuming they start a certain distance apart) will never collide and will maintain that exact distance they started apart.


What is the impact speed when a car moving at 100 kmh bumps into the rear of another car traveling in the same direction at 98 kmh?

The impact speed when the car moving at 100 km/h bumps into the rear of another car traveling at 98 km/h is 2 km/h. This is because the difference in speeds between the two cars is 2 km/h when they collide.


Will a smaller object traveling at a higher speed be more dangerous than a large object traveling at a low speed?

The answer will depend on their relative masses and velocities. But, as an indication, the kinetic energy of a body is m*v2 where m is the mass and v the velocity. So an object of a quarter the mass will have to travel at only double the velocity to have the same kinetic energy.


If the speed of an object does NOT change the object is traveling at a what?

It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.

What will happen when a car is traveling at steady speed?

That doesn't make sense. What do you mean, what will happen? Happen to what..?

If you were traveling at the speed of light in a car what would happen if you turned on the headlights?

Nothing


When traveling behind large trucks what should your following distance be?

This depends on your speed and may depend on what country you live in. Where I live you should travel at a distance suitable for the speed you are traveling.

Why traveling at the speed of light would we disperse?

No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).


If a car is traveling at the same speed for a long time it is said to be traveling at what?

cruising speed


Do large trucks take longer to stop than a car traveling at the same speed?

Yes. Because the truck is heavier.


What will happen when an object will try to travel at more than the speed of light?

Nobody knows for sure. We have never witnessed a physical object traveling faster than the speed of light.


Compare velocity from acceleration?

Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)


How long does it take to travel 557 miles?

It depends on how fast you are going. If you happen to be traveling at a speed of 557mp/h then it will take you one hour.


What would happen to the length of a meter stick traveling near the speed of light with its long dimension perpendicular to the direction of motion?

Nothing would.
