A lot of people think that 'velocity' is just a fancy word for 'speed', that you use
when you want to sound smart. But it isn't. The two words mean different things.
'Speed' just means how fast you cover distance. 'Velocity' means how fast you cover
distance and what direction you do it in. If you're driving around a circular track at
30 miles per hour, your speed isn't changing; but your velocity is, because your
direction keeps changing.
Two objects moving at the same speed but in different directions have different velocities.
Because their directions are different.
They would have to have different base velocities. One on the ground, the other in a moving vehicle.
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.

When they travel in different directions, obviously, since velocity is made up of a speed and a 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.
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.
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.
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Distance does not change the speed of objects.
=== === 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.
It depends on the observer's frame of reference. If both are stationary then an object's speed will be measured to be the same. If one or both are moving at unequal velocities, then the same object will appear to move at a different speed for each observer.
Momentum and is the product of mass and speed. So a fast-moving objects can have the same momentum as a slower-moving object with grater mass.
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.
Different objects can have different speeds; also, the same object can have one speed now, and a different speed later.
Relative speed is the speed between two moving objects with no regards to a fixed reference. Speed is how fast something is moving with respect to an object.
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
Different materials have different velocities of sound propagation.
ans: do you mean motion? motion is the meaning to move relative to something else, and it occurs (or is seen to be occurring) when two objects pass each other that have different velocities (not necessarily changing velocities). Without this, you would not be able to perceive motion at all. Motion doesn't mean speed has to change, as that relates simply to acceleration.
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
Take a train going west at 100 miles per hour and another train going south at the same speed. Their velocities are different because velocity is a vector quantity that gives both speed and direction. Since they are going in different directions they have different velocities.
The diagram you are asking for looks like two lines, with the same length, but pointing in two different directions. The difference in direction is what would show the different velocity. So imagine one line going down, one like going right, same length, but directions, so they would be different velocities.
A fast shutter speed enables a photographer to capture clear images of moving objects.
Reatively, they are moving at the speed of light, not above it.
It doesn't. It will change an objects direction and/or speed but its inertia that keeps it moving.
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
