Intermolecular forces are forces that act between molecules rather than interamolecular forces which act within a molecule these experiments show the differ. In this video i will introduce the purpose of the force table, a lab often encountered by first year physics students, and then breakdown the problem using newton's second law of motion category.
The us air force has set up a kessel run of its own in boston — a new lab focusing on developing mission-critical military software in record time. Lab 8: buoyancy and archimedes principle description in this lab, you will explore the force that displacing a ﬂuid (liquid or gas) will exert on the. The lab ideas and associated pages in the laboratory section of this web site are designed to help teachers improve their lab programs by adopting labs with a purpose there are over 150 lab ideas presented here - but their presentation is much different than the traditional presentation of a lab. Lab explanation and expectations this is a rotating station lab you will be timed when the timer goes off, move to the next station in numerical order for example, if you start at station 5, your next.
The force of friction we will be completing a formal lab report on the force of friction you will record a rough draft of the investigation in your science notebook. Purpose the purpose of this lab was to understand equilibrium to do this, you must find the equilibrant of the resultant of three vectors, both mathematically and graphically and test the results. This lab allows the user to visualise the gravitational force that two objects exert on each other it is possible to change properties of the objects in order to see how that changes the gravitational force between them.
Force lab teacher's guide objectives: 1 understand the relationship given by newton's second law 2 observe how friction can affect an experiment. Procedure units since each force involved is directly proportional to the mass hanging on the string, w = mg, you can for convenience in this lab record forces in grams a card with your apparatus gives the sizes and directions of two forces.
