## Homework Statement

Hi, I just started my kinetics course a few days ago and have a few questions about how to graph this and maybe help me out with some of the equations involved, I'm completely new to this and I got this test sheet a few days ago. thanks a lot guys

How do I graph this for the Position-Time Graph and my Velocity-Time Graph

for Position-Time Graph Do I start from the top of the graph (because it represents a free falling object) and make my curve or do I start from the bottom upward ?

## Homework Equations

my sheet also says

2.

**According to your position-time graph what type of motion did the object undergo?.**this would be Instantaneous Velocity correct? or maybe I should put Constant Acceleration?

4.

**construct a V-T graph using your data. Draw the line of best fit. calculate the slope of the line. what doe the slope represen**t

**?**Wouldn't their be more than one line, also the slope represents avrg velocity correct?

5.

**If accelerating is supposed to be 9.8 m/s2 [down], determine the percentage error of your value.**

% of error ={(measured value ? accepted value)/accepted value] x 100.could this be due to air resistance acting upon the falling object? also how would i go about calculating air resistance into my equation

% of error ={(measured value ? accepted value)/accepted value] x 100.

**6. State possible errors caused in your measured values. what techniques could be used to correct it?**maybe incorrect calculations? so a calculator

**?**

7. Use your V-T graph, and determine the maximum displacement of the object, does this match the height from which the object falls.I would say yes because if I'm correct my textbook says displacement is a vector and position is a scaler, the only direction the object goes is downward, so they would match? but how would I show that in my work
