Kelematics Lab Report

The graph I created from the tested data differs from my predicted graph. They both are positive as the time increases as the position increases, but in my predicted graph, I did not count for acceleration. The reason the graph is not a

1. Record: Select the BAR CHART tab, select Acceleration from the dropdown menu, and turn on Show numerical values. The bar on the left shows the magnitude of the acceleration, or |a|. The units of acceleration are meters per second per second, or m/s2.

The average rate of change is an average slope from the initial point to the final point. We would have to use A(x)=f(x)-f(a) divided by x-a to find the average rate of change. Sometimes we would want to know what the average rate of change is in the middle of the graph. The average rate of change is used in page 10, “How many more people?.” The concept of slope comes from the idea of a constant rate of change. To find the slope, you have to calculate y1-y2 divided by x1-x2. Slope is often denoted by the letter “m” which means that m+ equals the slope. Its problem is being used in page 21, “Rates, Graph, Slopes, and Equations.” Y=mx+b is the equation of the line that you can find using the two points. Variable “m” is the slope and “b” is the y-intercept.

9) Since you are plotting displacement on the y-axis and time on the x-axis, this is an example

If we measured in meters then a=4.9.) t is the time in seconds, v0 is the initial velocity of 30 feet per second, and s0 is the initial height or 4 feet. Thus we have:

Some of these factors are gravity, the air resistance, the speed of release, the angle of release, and the height of release. The most basic and principal factor acting on a projectile is gravity. Gravity affects every object. It decreases the height that a projectile can attain. Air resistance is also a key factor working on an object. The larger the surface area, the more air resistance will affect a projectile. Air resistance will also affect an object more if it has a smaller mass. Also, the faster the speed of the projectile, the greater the air resistance. The speed of release refers to how fast an object is released and is directly related to the distance of the flight. The greater the speed of release and object has, the greater the distance the object will have. The initial vertical velocity increases the height of trajectories, creating a longer flight path. Similarly, as the initial horizontal velocity increase, the longer the length of flight and distance. The angle of release is the angle that an object is thrown or hit into the air. It changes the relationship

After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v​i​​+at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this

A horizontal line on a distance-time graph means the object being graphed is not moving at all.

Before starting this project, we were familiar with graphing parabolas as well as examining distance and height due to a class activity and desmos practice we did prior to this. The class activity helped us understand parabolas by giving us a real life example. Then, moving onto desmos, we used our knowledge to graph out the parabolas with equations that were given. We used this to start our project so we could have an idea of how to graph our equation and where on the court(graph) we could triumphantly make the shot. We began by plugging in our equation to desmos by changing the a-value to -0.25 so it would resemble our equation. Doing this, the shape of the graph was not affected because Mr. Albert had the same equation as we did. Therefore, the shot was not affected, only when we changed the k and h values.

The sketch below shows the trajectory of a projectile propelled with an initial velocity V0 at an angle 8. Neglecting air resistance the horizontal range travelled is given

Projectile Motion is basically an object is getting launched in the air with any given velocity and angle due to gravitational forces. The kicker needs wind, because it helps the kicker push the ball forward when it’s in the air. Which makes the ball go further and higher. The wind creates a large amount of air resistance against

Lastly, the launch angle also has a great effect on the distance traveled. If projected at 90° the ball would only be thrown vertically upwards and back down to the person. There would be no horizontal change in position but a great maximum height. The greatest horizontal distance is reached between 40° and 50°. For this reason the launch angle affects the

A ship which can move at the velocity of v0 = (12, 6) m/s (x-axis: the West to the East) on the lake. The ship is now on the river which flows to the West at the speed of 5 m/s. (12 points)

Example: A staircase that rises 3 feet in a horizontal distance of 4 feet is said to have a slope of ¾.

All of these require energy, and energy is what physics is all about. There is kinetic energy, potential energy, conservation of energy, velocity, acceleration, mass, force, and gravity. Energy gives you the ability to do work. Energy is everywhere in nature
