Physics FC - S1W1 -Linear motion - Gwyneth Lenfest | Biblioteka

Welcome to Physics!! My name is Mrs. Lenfest and I will be your teacher this year. These formatives will form the backbone of your flipped classrooms, you will have one of these every week all year long.

Physics is the science of motion, so we are going to start at the beginning with some basic ways we can discuss motion - where something is, what direction it is moving, how fast it is moving.

It may be useful for you to keep notes when you are asked to watch a video or to read in your textbook. Pay special attention to vocab words and formulas. We won't be shying away from the math this year, but different students in the class will have different expectations in re: how much math you will be expected to do. For many of you, much of the math will be picking the right equation and learning to "plug and chug".

You should have noted a couple different equations. How comfortable are you with reading and understanding formulas?

He mentioned SI units, where SI stands for "système international", and that a SI unit we will use a lot is a meter. Which of the following do you think are SI units? (don't look this up, just gut-feeling it)

Juan is looking at google maps to get from one spot to another. there is a straight line path via the highway, and a backroads path that he is more comfortable with (he is a new driver and doesn't want to use the highways or frontage roads yet.) Which of the following statements are true (more than one can be true)?

The distance of the frontage road path is the same as the distance of the back roads path

the displacement of the frontage road path is the same as the distance of the back roads path

The distance of the frontage road path is greater than the distance of the back roads path

the displacement of the frontage road path is greater than the distance of the back roads path

the distance of the frontage road path is less than the distance of the back roads path

the displacement of the frontage road path is less than the distance of the back roads path

1

How would you describe the direction of the displacement of the frontage road path?

How would you describe the direction of the displacement of the back roads path?

For on-level students the math in this course should be confined to "plug and chug" problems. This means, determining the values required for a formula, and then plugging those values into the formula. The formula for speed is $s=$$\frac{d}{t}$ where s is speed, d is distance covered and t is time. A man drove 100 miles to Walmart, and 100 miles back to where he started. It takes him four hours (two there, two back), not counting the time he was doing his job. Find the total distance he drove

What is the displacement for the above question?

instantaneous velocity		total distance traveled divided by how long it took you
average velocity		how fast you are going at any particular instant
average speed		when your instantaneous speed doesn't change with time
constant speed		the change in position divided by the change in time
constant velocity		how fast you are going, and in what direction, you are moving at any particular time
instantaneous speed		when your instantaneous velocity doesn't change

Honors students (on-level you can answer, but you don't have to): match the symbols, equations and concepts

Stavka koja se može prevući		Odgovarajuća stavka
the slope of a line tangent to a position vs time graph		displacement
$\frac {distance}{\Delta t}$		change in displacement over time = velocity
		the constant velocity of the movement
the slope of a line on a position vs time graph		The average velocity
The slope of the line from beginning of the position time graph to end of the graph		the instantaneous speed at the time
$\Delta x$		average speed

Explain how velocity is different than speed, and why velocity isn't always just speed with a direction.

1

remember that set of questions above about the man driving to Walmart? Using the equation for speed where $s=$$\frac{d}{t}$ find the speed the man drove. You may use a calculator if needed.

1

Notice that the above is the average speed. Assume that at one point the man had looked down and saw that he was speeding at around 100 miles/hr, realized he was about to pass a police car, and managed to slow down in time. The 100 miles/hr represented his

Distance and displacement are two words that have a similar relationship as speed and velocity. If you run a mile on a track, how far have you gone?

you ran a mile

the track is a quarter mile long, and you just ran it four times, but you ended up at the same place you started. so 0 ft.

both of the above are true.

The man drove from his house to a store, and had a positive velocity. When he was going home from the store he had negative velocity. What do you understand the negative velocity to mean?

Honors Extension (you can answer if you are not honors, but you don't have to): the equation for acceleration is
considering what we have already seen for the equation for velocity and displacement, what are some things you can figure out about acceleration?

1

Consider each concept, and rate how you feel about it

The difference between distance and displacement
what does position mean
what the $\Delta$ stands for
how to calculate the displacement
the difference between speed and velocity
the difference between average speed, instantaneous speed and constant speed
how to read a position vs time graph
how to calculate velocity
why distance can never be smaller than displacement
why average speed can never be smaller than average velocity

I've got this
i'm fuzzy
so confused
