Yes. If in opposing directions, obviously. But if they were in parallel to each other, they could still touch and damage each others bodies.
However, two cars moving with the same velocity cannot collide.
Neither, and the impact would not be the same for both vehicles because of the differing amount of force each car is carrying due to the differing speeds (amusing the mass of the two vehicles is identical). The total force of the impact would be the same as one car absorbing the force of a 45mph crash.
Combined speed.
First of all, remember that it takes force to change the speed or direction of amoving object, but not to keep it moving at a constant speed in a straight line.Whatever the space ship's speed and direction are when the engine is switched off,it continues moving at that same speed and in that same direction, until some forcecomes along to change them. That force might be, for example, a gravitational one,if the space ship's motion brings it close enough to a planet, a moon, or an asteroid.
A moving object will continue moving in the same direction and at the same speed unless some force acts upon it. The only effective way to do this with a spacecraft is to eject mass away from it. By using combustible fuel we can eject mass at a high speed, which larger velocity changes than ejecting material at a low speed.
Their orbit is a smaller circle than the ones further out, and as long as they are moving at relatively the same speed they will complete each orbit faster. Check out the planetary orbits link, it gives a really cool description and moving diagram
Sir Isac Newtons first law of motion The law of inertia an object in motion remainsthe same unless acted upon by an external force.In space there is no force to slow itdown so it keeps moving the same speed it was when the rockets stopped burning.In other words:No force is required to keep a moving object moving, as long as there's nothing actingon it to make it stop.
Its moving. Quickly. It is in orbit around the earth, the same as any satellite.
If they collide head on, the wreckage will remain at the point of impact (real world considerations aside).
Momentum will be conserved (it always is conserved). If the cars also move at the same speed, and the collision is inelastic, they will both stop completely.
Huh? If they are both moving at the same speed neither is faster.
Of course.
The product of the car's mass and its speed must be the same for both cars.
Assuming the impact was elastic, Car1 will not be at rest, and Car2 will move at 20m/s at the same direction Car1 was previously moving.
EK=.5mv(squared)The faster something is moving, the more energy it is considered to have. When two objects collided, that energy doesn't just go away, it needs to be transformed or transfered, and that is exactly what happens.When 2 vehicles collide, the kinetic energy they had is used to bend metal, create heat, and do other destructive things. The faster the cars are moving, the more energy they have, and the more energy for destruction they have.
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.
Speed - but NOT velocity.
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.

The object that is moving faster will force the other object in the direction in which it's moving If they are moving at the same speed, Newton's law of conservation says that they will have an equal and opposite reaction. If they don't collide head on, they will spin after contact in an unpredictable way.
