''Modeling Acceleration''

 

-This picture shows a ball and a graph, this shows acceleration is the graph is measuring position and time and also how far it travels.

-Its a good model to show how the ball moves in terms of ''Acceleration''.

-I can tell the differences in accelerations of its angle of slope which reads (-20) ,you can change the slope anytime means it also changes the graph.

''Acceleration''

Q1.What is similar about the two vehicles is both have a ''Constant Velocity'' of 30mph. And in the same direction, like going north to the same stop. One difference is the ''Speed'' of their ''Acceleration'' the sports car has a more ''Positive Acceleration'' than the school bus because of how it was created for example the school bus was not to look cool and tear up the streets it is to pick up passengers for work or school.Another example would be the bus and sports car size it looks like the bus is really heavy making itself have a ''Negative Acceleration'' in ''Speed'' with the sports car.

Q2. One similarity is the school bus and the sports car is they both have the same speed if the brakes were hit not at the same time for example the sport's car brake were hit 2.5 s earlier than the bus.Another reason is as the  sport's car stop first , the bus will reach the sports car's distance, for example in a 20 m road the sports car stops at 15m at the stoplight the bus will catch up a little later in 5s . One difference is the sport's car will get there first because of the difference in ''Speed'' the two share for example the sports car traveled 5m faster. Another reason is if a person was driving in each one and hit the brake at the same time it is likely that the bus will stop first because its balanced, and the sports car will take little more time to stop like 3s late for example.

''Guess method''

1. G
   In the response question the variable with units are given, what you need to do is provide your anwser with variable and units given from the response.

2.U
   In a response question there are always a problem, so as an anwser we have to have a variable= ? this is what are you trying to find.

3.E
   As you have the units and the variables with units given all you need is the formula to help solve the problem.

4.S
    If you have your formula all you need to do is plug in what is given it needs units.

5.S
   Now anwser your formula step by step and include units in your anwser.

''speed and velocity''

Speed: is the movement of a person,object, or thing it measures the movement how fast or slow it goes.

Velocity: measures the speed per second.

One example of Average velocity is when i am walking outside around the east Boston high school for a period of time until my dad comes to pick me up he drives 40m/s say i walk like 50 meters in all around the school building how long did it take me?.

One example of instantaneous velocity is turning on the light switch in the kitchen takes one second to turn it on.

''Distance vs. Time graphs''

- In class we in different teams each have a computer with a motion detector and all of us had a worksheet and board started walking away or foward to the detector to collect data on how to create the graph said on the worksheet, to do that we have to test what are we going to do as a team individually, and then anwser the question in his or her notebook.

-The graphs would be necessary of how our body moves physically and the time to take us to move fast, slow, and stop. It can also mention reaction time because the graph shows how quickly you are supposed to move or stop.
