is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating that the net movement of water moves into the said solution whereas a hypertonic solution is one with a higher osmotic pressure‚ thus the net movement of water will be

When transferring the acid from the mortar to the flask by washing it with water‚ the low solubility of the acid made it hard and some of it was still stuck in the mortar and was not transferred into the flask. When phenolphthalein was added

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:
