You have 3 categories: speed, both, and velocity.
under speed:
- is not a vector
- describes a rate
under both:
- describes how fast an object moves
- includes time
- includes distance*
under velocity:
- includes direction
- is a vector
*Speed is actually DISTANCE over time, while velocity is DISPLACEMENT over time. Just clarifying, because it might cause more confusion although displacement is essentially still a measurement of distance but is still quite different.

What is initial velocity?
Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
What is labeled diagram?
A diagram of which all the parts of picture have been labelled by their name is known as labelled diagram for e.g. in the diagram of human body the parts like head neck limbs are labelled
What does a bar diagram look like?
one dimensional
If the speed is steadily increasing what will the line representing speed look like on the graph?
Not curved.
What does a horizantal line mean on a speed time graph?
I would like to state first that you misspelled horizontal. The answer to your question is Constant speed.
If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
What does a venn diagram look like for velocity acceleration average speed speed inertia momentum?
Look it up on Google! This website is not an answer book. People are so lazy... So are you...it is called Answers.com right?!??!
What factor is the difference between speed and velocity?
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE
What is different between speed and velocity?
Speed is a scalar quantity that refers to how fast an object is moving, whereas velocity is a vector quantity that refers to both the speed and direction of an object's motion. Speed is the magnitude of velocity.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
Can speed of a body change if its velocity is constant?
No, if the velocity of a body is constant, then its speed cannot change. Speed is a scalar quantity that represents how fast an object is moving regardless of direction, while velocity is a vector quantity that includes both the speed and direction of motion. If the velocity is constant, then the speed remains the same.
Is the magnitude of instantaneous velocity always equal to the instantaneous speed?
Because speed is the magnitude of the velocity vector. The velocity consists of the speed and the direction, and the whole thing can be embodied in a 3D vector. If you like the velocity is the magnitude (the speed), which is a scalar (just a real number), multiplied by a unit vector in the right direction.
How are speed ande velocity similar?
Velocity has a magnitude which is it's speed, but speed does not have a direction like velocity. Velocity and speed both have a speed. The direction is designated by a vector. The speed of light is a speed it is a scalar, a velocity will be denoted by vector elements e.g V = IVx + JVy + KVz or V 1R where 1V is the unit direction Radial and V is the scalar speed. Some people think the + or - sign gives direction toward or from the origin. That is true but + or - does not make the quantity a vector.
What are the differences between speed and velocity?
Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to both the speed and direction of an object's motion. Speed is measured in units like miles per hour, while velocity is measured in units like meters per second north.
Can an object have a varying speed it its velocity is constant?
No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that includes both speed and direction, so if the velocity is constant, the speed cannot change even if the direction does.
Moving at constant velocity is also moving with constant speed?
Yes, when an object is moving at a constant velocity, it means it is moving with a consistent speed in a straight line. Velocity includes both speed and direction, so if the direction remains constant, the speed must also remain constant.
Velocity and speed?
Velocity is how fast and what direction. The formula for this is distance over time, indicating the direction. (North East, South or West.) Speed is how fast something is moving. Speed is like velocity except velocity indicates direction. The formula is distance divided by time. Hope that helps. :)
