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.
Same speed, same direction.
Two objects moving at the same velocity are moving at the same speed and in the same direction. If you're sitting on either of them, the other one appears to be motionless.
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
Yes. Consider both the objects to be moving with the same velocity in the same direction. Then, the velocity of one of the objects with respect to the other is zero and vice versa, i.e., relative velocity is zero. If the relative velocity is zero,i.e., one object appears to have zero velocity (no velocity) with respect to the other, then they are considered to be at rest with respect to each other.
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
if there is a balanced force on a moving object (no unbalanced force) the object will continue moving with the same velocity
Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
