Before the impact of the fluid onto the plate, the fluid is in line with the x-axis, as shows by the velocity vector labeled V1. After the water impacts with the plate the velocity vector V2 is the parallel to the x-axis. The equation to fiqure out the normal force on the plate is: Fx=ρQV1 Where ρ Is density, Q = flow rate and V1 is the x-component of velocity Force measured (1.4) this is a diagram of the weight arm and pivot used in this experiment. Using this diagram two equations can be found and used. When the valve is closed, no water flows and so the weight is positioned at distance L from the pivot.
For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.

Buoyancy Lab Report I. Theory: In this experiment, we are trying to prove a theory that buoyancy is a force exerted by a liquid, in this case water, which opposes an object's weight. The theoretical buoyant force is given by FB=ρgV with ρ is density (kg/m3), g is gravitational acceleration (m/s2), and V is volume (m3).To measure the buoyant force, we compare the weight of an object in and out of the water by FB=Wout – Win. The simplifying assumptions are no surface tension, no friction, no air resistance, and gravitational acceleration is constant at 9.8m/s2. II.
The osmotic pressure coefficient must be determined for different solutions. It has been determined by various researchers and investigators to be less than unity and slightly increases with increasing solution concentration if the solute is not known or it is complex, we have to use mass concentration instead of molar concentration. For convenience: this model assumed to be at a constant temperature and is incorporated with the other constant Y which simplifies osmotic pressure to solute concentration coefficient. The value of Y was assumed t-o be constant over the operating range of the solute concentration. In corporation of osmotic pressure equation into the expression for the solute flux Eq.

Reflection Laboratory OBJECTIVE The purpose of this lab is to determine if light obeys the law of reflection on various surfaces. The law of reflection states that the angle of reflection equals the angle of incidence. THEORY Reflection is defined as the change in direction of a light wave between two different media. There are two types of reflection, specular reflection and diffuse reflection. Diffuse reflection is one that is on a rough surface.
Newton’s second law of motion is expressed as a mathematical equation: Fnet = ma (Force = mass*acceleration) A significant notion of this equation is that an object accelerates in the direction of the new force, and acceleration is created by the net force. The SI unit for force in the above equation is Newton (N), SI unit for accelerations is metre per second squared (m/s2) and the SI unit for mass is kilograms (kg). The objective of this experiment was to show the relationship between acceleration and force in a frictionless environment and to show the concept of mass (Lab#1). Other equations used in this experiment were: V22 = V12 + 2ad; used to find the acceleration for each weight V1 = Lt1 and V2 = Lt1; both used to find the acceleration Materials * Two vernier photogate timers * String * Glider * Blower * Air—cushioned track * Weights and Hanger * Pulley and clamps * Vernier Lab Pro Procedure and Observations 1. Two photogate timers, 60 cm apart, were set over the air track.
