Tangential Velocity Lab Report

The name of the lab is “Drops on a Penny.” I was expected to find the independant variable, dependant variable, write a hypothesis, and test the experiment. After testing the experiment multiple times, I needed to find the average amount of drops for each trial, graph them, and tell what kind of relationship it is. The last thing I needed to do was rewrite the details of the project and write a conclusion. The point of the experiment was to have the students get used to the idea of a lab, and get familiar with independent and dependent variables.

Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.

Data Analysis Does the mass of a pinewood derby car affect the speed? If the mass of a pinewood derby car affects speed then the more mass the car has, the faster it will go. The procedures for the experiment were; Go get a pinewood derby track, car, scotch tape, quarters, and a timer. Set up the track. Make the derby car with the instructions included with the kit.

In the first activity, I determined the circumference and tangential speed of points on spinning DVDs to demonstrate the rotation curve of a rigid body. For instance, the DVD with a radius of 4 has a circumference of 25.13 cm and a tangential speed of 1933.08 cm per second. During the activity, I noticed as the radius increased, the tangential speed also increased. I also noticed the shape of the rigid body rotation curve was linear.

PACE TECHNICAL PAPER ROUGH DRAFT This experiment was conducted in an attempt to have wooden baseball bats brought back to NCAA and high school and children’s leagues, too. The experiment idea was to set up a pendulum where the bat swung down and hit the ball in the same spot every time. Then I measured where the ball hit the ground.

Which of the following unit is used to indicate mass? a. Cm3 b. Um c. Mg d. mL 21. Which of the following demonstrate a chemical reaction of water?

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 variable for each experiment will be the brand of toilet paper otherwise, for each experiment everything else will be

8) Explain how each experiment type (question 7) differs from the

What would the effect of a Lego with rubber edges do to the amount of foot injuries? Purpose: The experiment is to find a way to make Legos safer for children and parents to step on when the Legos are not put away and to prevent injury such as cuts, scrapes, and fractures. “The foot fracture was early diagnosed in 26 (55.3%) patients, but delayed in 21 (44.7%).

The main strength of conducting this experiment is that is shows the behavior exactly as it occurs in the real world.

The instructor has achieved her goal of teaching her students learning target 3-PS-1: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an

The time it took for each of the trials was a recorded and then based on that along with the radii measurements the calculations for the centripetal force were conducted. The purpose of this experiment was to measure the period of a swinging stopper for three selected radii in order to calculate the centripetal

This experiment has to be carried out carefully

The machine was set to 0 the force before the specimen was set into the machine. Each specimen was set into the machine, lining up the bottom of it with the the second pair of dots on the grasp. The top grasp was lowered to line the top of the specimen with the second row of dots on the upper grasp. Once in place and tightened, a strain gauge was attached to the specimen to measure how much
