Speed is the time rate of change in distance, s= d/t. Velocity is the time rate of change in Displacement v=D/t. The difference is distance d is a real/scalar number and Displacement is a vector number having distance and direction.

Is distance time and force velocity quantities?
Distance and time are quantities that define SPEED. Add Direction and you now have a Velocity Vector. Force is not in either definition, but is necessary to achieve a speed or velocity.
Define speed as a rate and define velocity as speed in a given direction?
Velocity of a body is the distance travelled by it per unit time in a given direction. Velocity is a vector quantity as it has both magnitude as well as direction. Speed of a body gives us idea of how slow or fast a body is moving. Speed of a body is the distance travelled by it per unit time. formula for speed is given by : Distance travelled/Time taken
How do you define of acceleration?
It actually means this. Increase in the rate or speed
It can be important to know the velocity of an object not just its speed because?
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 ...
What is the definition of speed and the definition of velocity?
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
Velocity differs from speed in that velocity indicates?
Velocity is a vector quantity, which means that a body's speed and direction are both required to define it. They are different because: Speed is the rate of change of distance with time but velocity is the rate of change of displacement with time.
Is distance time and force velocity quantities?
Distance and time are quantities that define SPEED. Add Direction and you now have a Velocity Vector. Force is not in either definition, but is necessary to achieve a speed or velocity.
Can the speed of body be negative?
The problem here is the conflating of the term "speed" with "velocity". Velocity is a vector - it has both intensity and direction. Velocity can be negative. Speed really only has magnitude, so it is normally only positive; since there is no direction associated you can't define a meaning for negative speed (unless you decide to define it as synonymous with velocity) When a body is thrown in upward direction and upward motion is defined as positive velocity, its velocity decreases with time and at highest point speed and velocity become zero. When the body falls downward its speed i increases until hit the ground but since it is moving in the opposite of the direction that was defined as "positive", its velocity is negative.
Define speed as a rate and define velocity as speed in a given direction?
Velocity of a body is the distance travelled by it per unit time in a given direction. Velocity is a vector quantity as it has both magnitude as well as direction.

What is an angular speed of a rotating body?
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
What is the definition of speed and the definition of velocity?
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.
The speed and direction of a moving object determines the what of an object?
You might be referring to velocity. It is a vector physical quantity and both speed AND direction are required to define it. One can also consider velocity as the rate at which an object changes position.
What is the name of the speed with direction?
Velocity is the measurement of the rate and direction of change in the position of an object. It is a vector quantity; both magnitude and direction are required to define it. The scalar value of velocity is speed. For example, a speed of "5 meters per second" is a scalar and not a vector measurement, whereas a velocity of "5 meters per second east" is a vector measurement stating both speed and direction.
What is the biggest difference between speed and velocity?
velocity is speed with direction; velocity is a vector and speed is a scalar
What is speed in a given direction is called?
Speed in a given direction is velocity.
