Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.

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.

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 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.

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.

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.

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.

When two waves travel in a medium with the same speed and frequency but opposite velocities.

When they travel in different directions, obviously, since velocity is made up of a speed and a direction.

Two or more velocities can be combined by using vector addition.

If their velocities are equal, then the speed of each bus relative to the other is zero. A passenger on one bus could read a newspaper held up by a passenger on the other one.

If the velocities are equal from my point of view, then I see them both moving at the same speed and in the same direction. That means that from the point of view of an observer riding on either body, the other one is standing still. Their relative velocity is zero. This is exactly the situation with a passenger and the book she's reading, both in an airliner flying west at 400 mph.

A resultant velocity is the vector sum of two or more velocities (remember that a velocity has both speed and direction).

They fall at the same speed even if the mass is different that is upon a vaccum mass wont matter velocities would be equal as gravity acts uniform to al objects.

that is because velocity is relative. If two cars are traveling in same direction at same speed relative speed is zero. If two cars are traveling in opposite direction at same speed the relative speed is twice as fast..

The velocities of the two bodies after the elastic collisions are given by V1=(M1-M2)U1/(M1+M2)+2M2U2/(M1+M2) V2=(M2-M1)U2/(M1+M2)+2U1M1/(M1+M2) Where, V1,V2 are the velocities of the two bodies after collision. U1,U2 are the velocities of the two bodies before colision.(U1&gt;U2) M1,M2 are the masses of the two bodies. when the mass of two bodies are equal that is M1= M2 then V1=0+2MU2/2M=U2 V2=0+2MU1/2M=U1 Thus when two billiard balls of equal masses undergo perfectly elastic collision the velocities the two bodies are interchanged after the collision.

There is more kinetic energy in the collision involving the high-speed cars than there is in the collision involving the low-speed cars, resulting in a greater amount of force exerted on each car, prompting more damage.

No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.

No. The speed is the same, the velocity is not. The term "velocity" includes the indication of the direction. Two velocities are the same if they have the same magnitude (e.g., both are 40 km/hour), AND the same direction.No. The speed is the same, the velocity is not.
