Investigating the water potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis, by finding the difference in weight before and after the potato has been set in a solution of water, sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel, potato cutter, and test tubes. Then

speed and mass to name a few. The design of the catapult denotes a change in modern warfare to the engineer behind weapons being just as important as the actual soldiers and people who use them. Projectile-throwing machines are found in three main

Investigate the Osmosis of Potato Cells in Various Salt Solutions Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is not

Aside from being one of the most accessible (and best!) sports out there, many aspects of bowling can be expressed with physics. Achieving maximum power, throwing a hook ball, and getting good pin action can all be broken down into physics issues and represented with equations. I will cover four aspects of bowling that can be explained with physics terms and show you how to use this knowledge to optimize your game. Gravitational Potential Energy Depending on the height from which the bowler

Fifth through eighth beat- repeat previous four mirroring the direction, leader does what the follower did and vice versa Now let's find the center of mass in the x direction at the pause in this step. The equation for the center of mass in the x direction is xcm=(Mx1+ mx2)/(M+m) where M is the mass of the leader, m is the mass of the follower, x1 is the position of the leader,and x2 is the position of the follower. Turn The turn starts off with the follower and the leader side by

Nutrition in Mountain Biking I. Waterworld 1. Muscles produce 30-100 times more heat while riding 2. Water doesn't supply calories, minerals, or vitamins A. But it is used for almost every body function B. 55-65% of body weight is water 3. When losing a quart of fluid heart beats 8 more times a minute 4. Before a long ride start hyperhydrating 1 day in advance 5. Do drinking strategies during your training II. Rehydrate 1. Drink alot after a ride 2. Sports drinks replenish the best 3.

The Physic of Paintball I.The Fundamentals of the Game of Paintball. Paintball is a sport that is still fairly new in the world being not much more that a decade old. This game as with other sports would not be possible without physics. Physics is essential to the game of paintball. Some of physics that are involved in paintball are pressurized gas, projectile motion, and the impulse of being hit by a paintball. As with all sports there is necessary equipment needed to play. The most

examine a free body diagram of this situation. One may now clearly see why Joe does not accelerate downward while he remains is in the plane. The normal force of the plane is acting against the normal force of the gravity acting on Joe's 100 kilogram mass (this is getting close to the maximum weight allowed for skydiving). Since the sum of the forces in the y, or upward direction, is equal to zero, there is effectively no force acting on Joe. Thus, the acceleration of Joe must be zero. Now that Joe

happening) 4.2*3.7sin(33)*9.8 Bar and Weights A beam of mass mb = 10.0 kg, is suspended from the ceiling by a single rope. It has a mass of m2 = 40.0 kg attached at one end and an unknown mass m1 attached at the other. The beam has a length of L = 3 m, it is in static equilibrium, and it is horizontal, as shown in the figure above. The tension in the rope is T = 637 N. a) Determine the unknown mass m1, at the left end of the beam. Sum of the forces = 0 because the

The next step, as mentioned above is changing the steer’s direction. This is done by using the steer’s momentum and his horns. In this process I will discuss the laws and ideas of torque, centripetal forces, and the idea of center of mass. As I mentioned in the paragraph above, I will first discuss the collisions involved in the sport of steer wrestling. To properly discuss the collisions let’s talk about he linear momentum involved in the sport. There are two things that carry momentum
