please check if these are right
1. Which of the following is the equation for average velocity?
a. Vavg=delta x/delta t
b. Vavg=delta t/delta x
c. Vavg=delta x *delta t
d. Vavg=V1-Vf/2
i picked A
2. Suppose you are given a position versus time graph. the slope of a line drawn tangent to a point on the curve of this graph describes what quantity?
a. acceleratio
b. desplacement
c. instantaneous velocity
d. position
i picked C
3. Acceleratino is defined as
a. a rate of displacement
b. the rate of change of displacement
c. the change in velocity
d. the rate of change of velocity
i picked D
:)
All your answers are correct
thnks. please look at my post below this..i thknk i did something wrong
:)
Let's check your answers:
1. The equation for average velocity is the ratio of the change in position (delta x) to the change in time (delta t). So, the correct equation is option A: Vavg = delta x / delta t. You picked the correct answer!
2. When you draw a tangent line to a point on a position versus time graph, the slope of that line represents the instantaneous velocity at that particular point. So, the correct answer is option C: instantaneous velocity. You picked the correct answer!
3. Acceleration is defined as the rate of change of velocity. So, the correct answer is option D: the rate of change of velocity. You picked the correct answer!
Great job! Your answers are all correct. Keep up the good work!
