Mar 31, 2022 · The velocity vs time graph (in the middle) shows you how quickly something is moving, again relative to an observer. Finally, the acceleration vs time graph (on the right) shows how quickly something is speeding up or slowing down, relative to an observer.
Based on the data in the table, which statement is correct? The overall reaction is H2(g)+2ICl(g)→2HCl(g)+I2(g); the rate law for step 2 is rate=k[HI][ICl]. Since the rate law can be expressed as rate=k[A2][B], doubling the concentrations of A2 and B will quadruple the rate of the reaction.

What does the area under acceleration versus time graph give you?
What the area "is" depends on what the graph is. If the graph is velocity vs time, then finding the area will give you displacement, because velocity = displacement / time. If the graph is acceleration vs time, then finding the area gives you change in velocity, because acceleration = change in velocity / time.

- What does negative acceleration mean? Does is mean that the object is slowing down?No, a negative acceleration just means that the acceleration is in the negative direction. If an object is traveling in the direction that is consi...

Dec 17, 2019 · Calculate velocity and speed given initial position, initial time, final position, and final time. Derive a graph of velocity vs. time given a graph of position vs. time. Interpret a graph of velocity vs. time.
or. x = x0 +v–t. x = x 0 + v - t. 2.91. Thus a graph of position versus time gives a general relationship among displacement (change in position), velocity, and time, as well as giving detailed numerical information about a specific situation. The Slope of x vs. t. The slope of the graph of position x x vs. time t t is velocity v v.
Distance-time graphs are graphs that show the distance an object or person has travelled against time. They can also be referred to as travel graphs. A distance-time graph will show the distance (in metres, kilometres, miles etc.) on the vertical axis ( y y -axis) and the time (in seconds, minutes, hours etc.) on the horizontal axis ( x x -axis).
B-C. A person decides to graph the time and speed traveled during a family vacation. The results of the graph are shown. 20 km/h. Study with Quizlet and memorize flashcards containing terms like 1) Select the correct answer based on the graph., Quinn goes for a bike ride.
