Speed/acceleration
Speed in a specific direction is known to be " VELOCITY "
A force must act on an object to change it's speed, direction or both. This is Newton's Second law.
The answer is velocity.
Velocity vector.
its called velocity.
velocity is the right answer
In physics, if both the speed and the direction are specified, the term "velocity" is used.
I think u guy talking about velocity velocity is often confusing with speed but it is differnt from each
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
average velocity
Speed is an absolute unchanging linear distance crossed per unit time. Speed is not the same thing as velocity, and an object cannot exhibit a "rate of speed" since rate is velocity. Speed is determined by measuring the distance traversed over a specific unit of time. Since the object almost always is not at a constant speed, we are really estimating the average speed.
Short answer: yes. An object in "motion" has a "speed" simply by virtue of its being in motion. An object possessing a speed is inherently in motion. In this sense they have similar meanings. Speed is a rate of change in position. Motion is a change in position (in progress). In this sense, speed is more specific than motion in that speed has a quantitative value. Conversely, there can be no "speed" without "motion". To be complete, "velocity" is even more specific than speed in that it contains a rate of change in position together with a direction. That is, speed is a "scalar" quantity, and "velocity" is a vector quantity.
Yes it is. That definition is correct.
