Hess’s Law Mengyuan Wu (Millie) 7 January‚ 14 Aim: The purpose of this experiment is to determine the enthalpy change for the reaction: Introduction: It is impossible to measure the enthalpy change for this reaction directly because the process cannot be controlled. However‚ you can calculate this enthalpy change by using the Hess’s Law. Pre- lab Calculations: Calculation 1: Required Masses for Reaction The ratio of and is required to be 1:100 for Table 1: Calculation

Term 3 Uniform Circular Motion When a body moves in a circular path with a constant speed‚ it is said to undergo uniform circular motion. Although the speed is constant‚ velocity is continually changing‚ since it is constantly changing its direction of motion. Centripetal V V ac ac Acceleration is directed towards the centre of the circle and is therefore called “centripetal acceleration.” ac =v^2r ac =v^2r If T is the time taken for one revolution then: V = 2πrT ac =v^2r

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Some would also consider his writing habits were too out of the ordinary. For example‚ Brahms liked to write his symphonies or whatever he would be working on during the warmer months like in the spring and summer time. Then he would spend the cooler months going out

Title Projectile Motion Abstract A projectile was fired from atop an elevation and an angle. The initial velocity for each firing was likely to be the same. The distance traveled in the horizontal direction was measured for multiple firings of each trial‚ and the values were averaged. When the initial velocity for each of these averages was calculated it was proved that the initial velocity was relatively constant. These measurements had many possible sources of error including air resistance and

Projectile Motion PHYS111 Formal Report 2 University of Canterbury Campbell Moulder Abstract The force of gravity is said to be a constant of 9.81 ms-2 (3). This can be proved by measuring the projectile motion of a bouncy ball and plotting a ∆Vertical Velocity vs. Time graph‚ the gradient of which should equal the constant force (acceleration due to) of gravity. Our gradient value of 10.26±0.49 ms-2 is consistent with the actual value of 9.81 ms-2. Introduction A projectile is an

2. LINEAR MOTION In this experiment you will study the motion of an object in one dimension from a number of points of view. You will demonstrate how the variables of motion are related by differentiation and integration and investigate the relationship between potential and kinetic energy. Theory Why Study Motion? Motion is everywhere in the universe. Only at a temperature of absolute zero is the motion in any body truly absent. If motion exists then so also does energy. To the delight of

Classroom Tutorial‚ we learned a variety of means to describe the 1-dimensional motion of objects. In Unit 2 of the Physics Classroom Tutorial‚ we learned how Newton’s laws help to explain the motion (and specifically‚ the changes in the state of motion) of objects that are either at rest or moving in 1-dimension. Now in this unit we will apply both kinematic principles and Newton’s laws of motion to understand and explain the motion of objects moving in two dimensions. The most common example of an object
