Velocity= Distance/time or V=D/T. there is a triangle to help remember this
D
-----
V | T
permutations: V=D/T D=V X T T=D/V
Velocity is speed with a direction vector. Speed is distance per unit time without
any specification regarding direction. Velocity is speed plus a direction
component. The particulars might become easier to see when considering a
problem like what is happening when a shuttle is in orbit. (Gravity on the
orbiting shuttle and its crew is something like 85% of what it is on the earth's
surface, but the vehicle and the astronauts are weightless. What's up with
that?)
Velocity and speed are not synonyms.
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
Velocity.
No. Velocity includes a direction vector, which speed does not have.
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
no
distance over time equals the speed/velocity.
Speed times time equals distance
To find the average velocity of a projectile, use V = D/T (Velocity equals Displacement over Time).
Kinetic energy equals 1/2 mass times the velocity squared, so mass and velocity (speed)
The average speed of motion is when speed is changing. Speed equals total distance divided by total travel time. Velocity is the speed and direction of an object's motion.
Speed is a scalar quantity with out direction, velocity is a vector quantity with a direction, The magnitude of a velocity, |V| is its speed. So all velocities have a speed, including a speed of zero.
speed divided by distance is time; or distance equals speed x time. Not sure of your question, but If speed is associated with direction, then it is called velocity, which is a vector, whereas speed is a scalarquantity
velocity is speed with direction; velocity is a vector and speed is a scalar
