Motor Spin Experiment Report

505 Words3 Pages

Does the type of battery used to create a motor affect the time the motor spins? If the type of battery affects the amount of time the coil spins then the D-battery powered electric motor will spin for the longest period of time. The procedures were to create the motor and find a spot for the motor to spin. You also needed to keep track of the time the motor spinned. When the motor stops spinning record the time on a data table. The independent variable was the type of battery used for the motor. The dependent variable was the time the motor spinned. The control variables where the materials used other than the battery. The control group was the D-battery and the experimental group was C, AA, and AAA-Batteries. The experiment had 3 trials for each motor. The D-Battery average time was 4 hours 29 minutes 45 sec. C-Battery average time was 4 hours 19 minutes 30 seconds. The AA-Battery average time was 1 hour 7 minutes 15 second. The …show more content…

The results also probably show that the smaller batteries had to use more force than the big batteries. An extraneous variable could have been that the tape making the poles and needle stay together got loose. Another extraneous variable is that the tape might not have been securely holding the needle and the top and bottom of the battery. The location of where the experiment was done could have made the results change. One of the observations was the C-Battery didn 't want to go at first but then started going fast. The D-Battey had some problems, it did not want to start spinning but after a few tries it started spinning. The C-battery also faced the same problems. The wire did not want to spin but ended up spinning really fast. The AA-battery faced no problem it just kept spinning. The AAA-battery like the D and C did not want to spin. The tape was loose so the motor did not want to spin. The tape was tightened and then it

4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse.

The difference between dependent and independent variables is that the independent is the variables that are changing or controlled in an experiment to test the effects on the dependent variable. In the Stefan-Boltzmann law experiment, for example, volts would be the independent variable while the radiation in millivolts would be the dependent variable. 7. What are the differences between qualitative and quantitative

7. In this experiment, if the sucrose concentration were increased to 70 g/l would you expect sucrase activity to be significantly higher than the activity at 35 g/l. Explain your answer. No, because based on the results once it reached 30 g/l 35 g/l the results had stayed the same. There, the activity is lessening and coming to what looks like a plateau. 8.

Alka Seltzer Experiment

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

HYPOTHESIS I hypothesized that a mousetrap car without a lever arm would generate more power, and a larger wheel diameter would result in a further distance. I believe that my mousetrap car will generate enough energy to travel fifteen feet. My mousetrap car is designed to quickly release energy and travel farther than most. However, the quicker release of energy can cause the car to steer towards the right. RESEARCH

Chevrolet Vs Ford Compare And Contrast

Ford became a first carmaker that installed a conveyor at its factory. This equipment made it the world’s first company that started mass car production. Chevrolet-490 was equipped with electric lights and starter; it was a rare decision even for more expensive models. Both companies worked on the improvement of the safety and other systems of their cars. But Ford demonstrated more conservative approach in some cases (at least, during Henry Ford’s ruling).

Are Elephant Afraid Of Mice Essay

493 Words | 2 Pages

In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.

VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.

The Electric Car: Advantages And Cons Of Electric Cars

1040 Words | 5 Pages

Effort is being poured into optimising this charging process but the fact is that with current technologies, it takes longer than fuelling a petroleum car. Estimates of how long, vary wildly depending on the battery, the source and charging methods but the general charging time seems to be between 4-8 hours1,2. While some charging estimates go as low as twenty minutes2 this is usually at the expense of the battery’s long term stability or something similar that would make it unfeasible for everyday use. The fact that recharging an electronic car is a process measured in hours means that the average consumer will be far more dependent on the range of a single charge. This effective range varies based on the size of the battery and which type of battery it is.

The starter engine is fundamentally an electric engine that gets the primary gas motor going. The start framework is the thing that touches off the blend of gas and air to deliver the burning the motor needs to keep it running. Everybody realizes that when the auto battery passes on, you can't begin it any longer. There can be numerous reasons an auto won't begin, however when you hear that clicking clamor, and no start, than it is most likely a dead battery.
