Veloicty is distance divided by time, for a object moving in a given direction. If direction is not given, then it is speed.
Tan@ y/x; @=atan (y/x)
Because work done is equal to the force times the distance travelled IN THE DIRECTION of the force. Distance travelled in an oblique direction can be decomposed into two components: s*cos(x) in the direction of the force and s*sin(x) in a direction perpendicular to it (where x is the angle between the force and the resultant motion). Motion in a perpendicular direction is NOT work done by the force, which leaves s*cos(x). Multiply by the force (as required) and you have your answer.
They define it as the product of how far the object goes multiplied by how much force that takes. (W=DF) It the force isn't lined up with the direction of travel, you have to use the formula W=DFcos(θ), where θ is how many degrees off the force is from the direction of travel.
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

Veloicty is distance divided by time, for a object moving in a given direction. If direction is not given, then it is speed.
direction, description, code, equation
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. :)

Mass (M) x Volume (V) is not the formula for anything. Mass multiplied by Volume is the formula for density. Mass multiplied by velocity (speed with a direction) is the formula for momentum.
a number derived from the formula for measuring a correlation and indicating the strength and direction of a correlation
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
WORK = FORCE x DISPLACEMENT
