No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.

Only if the two velocities are equal in magnitude but in opposite directions.

Both the gliders will be travelling at exactly the same speed as the initial velocity but in opposite directions.

Sometimes-when there masses are equal.

The combined VELOCITY of two cars that crash will be somewhere between that of the individual cars. In this case, the combined speed will be less than the speed of the car that was moving before the crash.If you know the velocities and the masses, the exact speeds can be calculated using conservation of momentum.

Momentum is equal to the product of mass and velocity, so if the mass is equal, the one with greater velocity has greater momentum.

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.

Generally, no.

No. Speed is the magnitude of the velocity vector. If velocities are the same, their magnitudes are the same, which is another way of saying that the speeds are the same.It can work the other way around, however ... same speed but different velocities, meaning same speed in different directions.

No the two buses do not have equal velocities because VELOCITY is the SPEED in a given DIRECTION. One would have a velocity of +30m/s because it is traveling in one direction, and the other would have a velocity of -30m/s because it is traveling in the opposite direction.

Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.
