# Can objects have equal speeds without having equal velocity?

speed is a scalar and velocity a vector. Yes, they have equal speeds in the direction of the vector. If you run up a hill at 10 mph the speed and velocity in the direction up hill are the same, but the horizontal speed and vertical speed are different.

Yes. Just have them move in different directions.

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.

We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...

No. Earth's rotational velocity is slowing. Do you mean the velocity of Earth's revolution around the sun? The earth speeds up in its orbit until it reaches perihelion, and then slows until it reaches aphelion.

Air friction is an example of fluid friction that is velocity dependent. It is caused by objects moving at high speeds through the air, and the air resisting it.

the velocity of an object changes when it speeds up or slows down.

Something that accelerates. It may refer to a particle accelerator - something that makes subatomic particles move at very high speeds.

"They've got different masses..." mass has no affect on the speed at which objects fall, objects fall at different speeds based on the drag created as they fall through air.

all objects fall at the same speed because i like ponies

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.

Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.

Yes The equation for momentum is mass x velocity So if you increase velocity the momentum increases

Air resistance. If there were no air all objects would fall at the same speed.

Convergent-divergent nozzles have the ability over convergent of raising the velocity to supersonic speeds whereas the convergent maximum velocity on exit is sonic. These speeds are beneficial to steam turbine efficiency. Kev Calvert

Yes, but not the other way round. If the two cars have the same velocity, both their speeds and the directions in which they move will be the same.

The Velocity can reach speeds of 200km/h, or 124/mph. It can also do 0-60 in under 3 seconds

In theory, yes, if an object is static it's velocity is zero. In practice, however, velocity of an object can only truly be determined in relation to at least one other object, so if only two objects are taken into account, there is no way to determine which one is moving and which one is static (or if they are moving in parallel, if both are moving, but at different speeds). When you start considering larger groups of objects (up to and including the entire universe itself) it would be impossible to find out from within the system whether or not the entire system is moving. Short version - yes, velocity can be zero, but it's impossible to tell for sure.

A relativistic velocity is a velocity that is close to or a significant fraction of the speed of light. At such speeds Newton's laws of motion lose accuracy and it becomes necessary to use Einstein's equations of special relativity to make accurate calculations.

I'll assume that you mean having it dropped on him, and the answer is no. Terminal velocity is the speed at which a falling body no longer speeds up due to air resistance ... for a pillow that's slow.

When an object speeds up, slows down, or changes direction, it is changing it's velocity, also known as accelerating.This is a common term in mechanical physics. The formula for velocity is D(distance) / T(time) whereas acceleration is the change in velocity which takes time to do making its fomula: D/T^2

no all objects fall at the same speed if they are in a vacuum the only thing that makes a difference if atmosphere or air.
