investigation was to find and verify the relationships between Centripetal Force‚ Frequency and Radius of circular path. In order to get relationships between the variables mentioned above‚ this experiment was divided into two parts. In Experiment A‚ the radius of the path (length of the string)‚ along with the mass was kept constant‚ and the relation between centripetal force and square of frequency was determined. In Experiment B‚ the Centripetal force and the mass were kept constant‚ and the relationship

DESCRIPTION The Centripetal Acceleration lab consists of using a pendulum bob swinging continuously. This will help see the F_max(tension) and F_(mean )(weight of the pendulum)‚ net force (N) and v_mean(velocity). RESULTS When starting the lab the first thing to do is to measure the cylinder properties (the bob) in table one. The measurements were: diameter (D) is .0815m‚ height (H) is .025 m‚ mass is .06591 kg‚ and the 〖Weight〗_theory W is .645918 Mg‚N. Second thing to do is to launch from

The point where the centripetal acceleration is provided completely by gravity is when the centripetal acceleration is equal to the gravity. This happens at the point where h=r/2. As the truck moves from point A to point B‚ it would have decreased in height by r. Applying this again to our equation‚ we get; Hence‚ Using this in our g-force equation‚ we get; And so the rider experiences an additional 2g of centripetal force from that experienced at the top. Later‚ as the tuck moves to point

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

Buoyant Forces The purpose of this lab is to calculate buoyant forces of objects submerged in water. The first step in the lab was to measure the mass of a metal cylinder‚ which was found to be 100g‚ and then to calculated it’s weight‚ which was .98 newtons. Then next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g ‚ this was found to be 88.5grams. Knowing these two numbers‚ the buoyant force that the water

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

Paperose Lab- Introduction to Enzymes Ms. Kim/Honors Biology Purpose To Determine the rate of an enzyme reaction using a “modeled” enzyme and sugar‚ paperase and paperose. Introduction In this lab‚ your hands are the enzyme‚ paperase. This enzyme split the sugar‚ paperose‚ into subunit A and subunit B. You will split this molecule by ripping the paper model down the middle. Materials Paperose models‚ scissors‚ plastic bag‚ container (large plastic cup)‚ stopwatch‚ Procedure 1. Each

yields two integrations: x = x0+v0t+1/2at2 v = v9+at These two expressions show the relationship between position‚ velocity‚ and acceleration at a given time. Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment‚ then the acceleration of the glider would be equal to acceleration of gravity multiplied by the angle between the air track and the horizontal table (g
