In summary, the instantaneous speed on a speed-time graph is obtained by finding the tangent at a specific point on the graph. This can be illustrated by the left numbers representing distance and the bottom numbers representing time on the graph provided. The graph that shows a constant speed for the whole trip is graph A, while graph B shows a constantly changing speed. Graphs A and C have an instantaneous speed of zero at some point. The instantaneous speed at 1.0 min for each graph can be found by finding the slope of the tangent at that point. Finally, the average speed for 0 to 5.0 min can be calculated by finding the slope of the line connecting those two points on the graph.

1.) How is the instantaneous speed obtained from a speed-time graph?

2.) I ADDED A PICTURE OF A TIME GRAPH USED FOR THESE QUESTIONS:

(the left numbers are distance, the bottom numbers are time (min)

A. which graph illustrates a constant speed for the whole trip?
B. which graph show a constantly changing speed?
C. which graph(s) has (have) an instantaneous speed of zero as some point?
D. what is the instantaneous speed at 1.0 min for each graph?
E. calculate the average speed for 0 to 5.0 min for each cyclist.

You have distance on one axis and time on the other.

What is speed? Is it distance divided by time by any chance?

At any point what is the rate of change? Isn't it the tangent at that point?
 

Related to How Do You Calculate Instantaneous Speed from a Speed-Time Graph?

1. What should I do if I can't figure out a problem?

If you can't figure out a problem, the first step is to take a break and clear your mind. Sometimes stepping away from the problem and coming back to it with a fresh perspective can help. You can also try breaking the problem down into smaller, more manageable parts and tackling them one at a time.

2. How can I ask for help in a more effective way?

When asking for help, it's important to provide as much information as possible about the problem you are facing. This includes any steps you have already taken to try and solve the problem, any error messages you have received, and any relevant data or code. This will help others understand the problem better and provide more targeted assistance.

3. Is it okay to ask for help when working on a problem?

Yes, it is completely normal and acceptable to ask for help when working on a problem. In fact, seeking help from others can often lead to new insights and solutions that you may not have thought of on your own.

4. How can I avoid getting stuck on a problem?

To avoid getting stuck on a problem, it's important to break it down into smaller, more manageable parts. This will make it less overwhelming and easier to tackle. Additionally, make sure to take breaks and step away from the problem if you find yourself getting frustrated or stuck.

5. What resources can I use to help me solve a problem?

There are many resources available to help you solve a problem, including online forums, tutorials, and textbooks. You can also reach out to your peers or mentors for assistance. Additionally, don't be afraid to use trial and error to figure out a solution and remember to always document your steps for future reference.
