7. Draw a diagram of this set up. Use arrows to depict the movement of each substance in the

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

A. How did the experiment in Part I demonstrate surface tension? Use your experiment observations when answering this question.

1. Find the westward component of a resultant vector 85.42 unit, 23º W of N.

1. A boy is whirling a yo-yo above his head in a counter-clockwise direction. At the exact moment shown at left, he lets go of the string. In which direction will the yo-yo travel? Draw an arrow on the image to show the yo-yo’s direction.

T= 40ms, I figured this by guessing cause I could not find any information on how to calculate. So I used the equation for t and plugged in different numbers until I got the 10ms that was already given in the table. t= T x 0/360= 40ms x 90/360= 0.01 x 10^-3= 10ms

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces. Part II

If the mass of the cart increases and the net force remains constant, than the acceleration will proportionally decrease because Newton’s second law of motion states that acceleration is equal to the net force divided by the mass of the system; this demonstrates an inversely proportional relationship between acceleration and total mass because as the mass increases, acceleration will decrease (Newton’s second law).

If a structure is in static equilibrium, then any portion or segment of it must also be in static equilibrium. With this

Seven various household objects were chosen to measure using a digital gram scale. Each object’s mass was estimated by lab students and recorded in data table 4. A quarter, ball point pen, rubber bulb, large paper clip, green crayon, house key and a copper penny masses were estimated and recorded in data table 4. Each object was placed on the scale individually and its actual measurement was recorded in data table 4. As we started estimating the household objects we were often not correct in our estimations. As we measured more and more objects, we got better in our estimations by comparing objects with known masses and comparing them with the unknown

6. After knowing A=B maybe the force is equal from the bug and the windshield. That’s the case with Newton’s third law

If the length of the incline plane increases then it will potentially take less force for the Aspire crew to lift and complete the task. The amount of work input varies on the length of the inclined plane the longer the ramp is, the less force will be needed to be exerted in order to lift the stone. Through a complete understanding of the concept through my research it is my understanding that the incline plane will decrease the force being applied but nevertheless it will increase the distance.

The magnitude of the forces exerted in the horizontal and vertical directions can be calculated using trigonometry. The total magnitude of the force multiplied by the cosine of its angle with the horizon will calculate the horizontal force. Conversely, the total magnitude of the force multiplied by the sine of its angle with the horizon will calculate the vertical force.

Step 8: We can now plot our values into the rearranged equation to figure out acceleration due to gravity ‘g’. (Eg. (4π2 x 43.70)/ 1.758 = 981.4 cm/s2)

Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.
