Is the rate vector or scalar? And And the average acceleration? What about instantaneous and average rates? Why? Is the rate vector or scalar? And And the average acceleration? What about instantaneous and average rates? Why? Why?
Velocity acceleration is a vector
Rate is scalar
Instantaneous and average speeds are vectors
Instantaneous acceleration and average acceleration are vectors
Instantaneous rate and average rate are scalar
Instantaneous and average have no effect on what quantity, velocity is the ratio of displacement and time, displacement has magnitude and direction, so velocity also has magnitude and direction, so is vector
Acceleration is the ratio of the change of velocity to time. The change of velocity has magnitude and direction, so it is a vector.
Rate is the ratio of distance to time, distance is only size, no direction, so rate is scalar
Was speed a vector or a scalar? What about the speed? Speed could be the ratio of displacement to time, or the ratio of distance to time. Displacement was a vector, and distance was a scalar. What about speed? Wasn't speed actually speed? Was it as fast as it was? Speed could be the ratio of distance to time. Distance was a scalar. Why couldn't speed be a scalar? The third floor is really powerful. Have you opened your high school textbooks? You must be wrong. I still feel that it can be both vector and scalar, dizzy Brother Feng Chen Haojie came to answer my question
Is there a mistake on the first floor, or is there a direction for your time? Time is scalar, velocity is the ratio of displacement and time, that is, V=X/T, displacement is vector, vector is scalar, vector is also vector, so V is vector, V and direction of displacement are consistent, velocity is not velocity, velocity is the magnitude of instantaneous velocity, only refers to size, does not refer to direction, so velocity is scalar, and velocity is not the same, as for instantaneous velocity, there is no need to explain it ==
Is the average rate scalar or vector
Average rate = distance/time, is scalar.
Is the instantaneous speed vector or scalar? Is the instantaneous velocity vector or scalar?
Speed is a vector, so is instantaneous speed
Rate is scalar, and instantaneous rate is also scalar
Is the instantaneous velocity scalar or vector?
Vector
"Speed is vector, instantaneous speed is scalar" right? Is that right? "Speed is a vector, instantaneous speed is a scalar," right? Is that right?
As long as the velocity is a vector, the instantaneous velocity is no exception. The instantaneous velocity is the change rate of a certain instantaneous displacement to time, i.e. V=ds/dt. Since s is a vector and t is a scalar, a vector should still be a scalar compared with the previous scalar. Only the velocity (the magnitude of velocity) is a scalar.
