Coulumbs Law Lab Report Essay

* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.

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.

C. If you are by yourself, simply throw the ball into the glove with as much force as possible.

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

              When doing this experiment, I used my senses of touch and hearing to predict what the

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

* The battery applies a voltage to the plates, charging one plate positive and the other plate negative. Alpha particles constantly released by the americium knock electrons off of the atoms in the air, ionizing the oxygen and nitrogen atoms in the chamber. The positively-charged oxygen and nitrogen atoms are attracted to the negative plate and the electrons are attracted to the

3. Test the effect of a magnet on each substance by passing the magnet under

3. Electrons are small and are negatively charged (-) with a mass of almost 0 amu..

Since the charge moves in the direction of the field, the field does the work

3. Bring the charged balloon close to the paper scraps from Part 2. How does the rubbed balloon

1) Use the Force Field Analysis or the Differentiation & Integration diagnostic model from Chapter 5 in the text to explain what is happening in this case. Include the appropriate chart/table.

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

The results of this experiment proved the plum pudding model of the atom to be incorrect as some of the alpha particles (helium atoms) deflected meaning the atom has a dense centre of positive charge. Particles either hit the positive

3) In this experiment, only the forces on the plane surface were considered. Do the hydrostatic forces on the curved surface of the quarter-circle block affect the measurement? State why or why
