Factors Affecting Speed Of An Object

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

The hypothesis about the CO2 angle will change the speed of the car was, rejected. The hypothesis was that if a Pinewood derby car had CO2 inserted at a 20 degree angle, then the 20 degree angle would work best because the angle would keep enough thrust power and keep the car on the track. However, the 20 degree angle was the second best because the 180 degree angle had more thrust power to it then the 20 degree angle. The control group was the 180 degree angle and it’s average was 1.33 second. The 45 degree angle was the longest with an average of 2 seconds. The 20 degree angle or second experimental group had an average of 1.67 seconds. I got these results because each angle that got farther from strait started to lose the amount of thrust that the 180 degree angle had. So if I tried it with a 90 degree angle then the car wouldn’t be moving at all.

In this series of experiments, we examined the back and forth motion. We analyzed the motion of five objects which included a mass attached at the end of a spring, a swinging pendulum, a ball thrown up in the air, a jumping student, and a cart rolling up and down an incline. Using the motion detector and a computer we were able to come up with graphs of position VS time and Velocity VS time from which it was possible to tell where the velocity or the acceleration were maximum, and whether they were changing or not. Besides that, the graphs also helped to notice objects that exhibited a similar type of motion.

To determine whether the height at which a marble is dropped affect the size of the crater.

rate of fall of an object was determined by its weight held that matter was constructed out

Next, the independent variable was the sail car and shed car. The speed acceleration was the dependent variable. The constants marble distance of photogate the angel of the track.

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

Some of the problems that our team is facing are the turns that we have to make. The marble is getting stuck because it is too tight. Another problem is the marble keeps falling off of the track. So we decided to build a paper tunnel so it will stay on the track.

7. Raise the inclined plane by two holes, making sure the angle also increases by 2˚.

3. Set up the ramp so that the highest point of the ramp is 10 cm above the top

We did this by measuring the length of the whole ramp, width of the bricks, and height of the nine and seven eights bricks the above the wall base . Our results concluded that the ramp was at a legal slope. The length of the ramp was seven hundred and seventy- five inches, the width of the brick was seventeen over eight inches, and the wall base was four inches and the height of the wall was nine inches of full blocks and seven over eight inches of another block. If you were to find the height of the wall you would multiply nine inches by seven over eight inches which would give you twenty inches and then you would subtract twenty inches by four inches which would give you sixteen inches overall. To find the angle you would use Sin inverse, which would be sixteen(opposite) over seven hundred and seventy-five (hypotenuse) and the overall answer would be one point eighteen degrees for the angle. The angle of elevation is parallel line the alternating interior angles are congruent to the angle of depression so they would be the same (one point eighteen degrees). Summarizing the conclusion, though the results could have been more accurate, we see that the ramp is still legally designed for a hand-propelled

The purpose of my science fair was to figure out what angle in shooting will produce the most amount of goals. First I chose which angle for shooting is more effective to produce the most amount of goals in a game. I chose this because in my games I have found that sometimes we miss the shots on goal, and I wanted to find a way to put an end to it. That's why I chose this for my science experiment. My results were that the 45 degree angle proved to be the best angle for shooting and -90 degree angle was the worst.

The aim of the experiment is to examine how the acceleration of the car differs when the angle of inclination of the ramp is amplified and to record and analyse findings.

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.

I chose this topic because it interested me and i did something similar to it last year. This year I am going to answer how does the surface on which a car moves affect how fast it travels.
