masses of the two particles‚ r is the distance between the two masses‚ F is the gravitational force between them‚ and G is the universal gravitational constant‚ . The above equation only calculates the gravitational force of the simplest case between two particles. What if there are more than two? In that case‚ we calculate the resultant gravitational force on a particle by finding the vector sum of all the gravitational forces acting on it: By adding the unit vector to the equation‚ F now processes

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth. During free-fall the only force that should be acting upon the object is the earth’s gravitational pull (9.8 m/s/s)‚ therefore the velocity of the object should always equal 9.8 m/s/s. In this lab the picket fence was dropped repeatedly through a photogate connected to Logger Pro‚ which allowed the fence’s acceleration and velocity to be recorded and graphed. The results of the experiment confirmed the

acting on it‚ and acceleration by gathering data through investigations. Hypothesis: As Mass increases‚ Acceleration Decreases. Therefore‚ Acceleration is inversely proportional to mass. Introduction A force is a push or pull acting upon an object‚ as a result of its interaction with another object. In a state of motion‚ an object experiences different forces which influences its movement. There are many different types of forces which act upon an object; a normal force‚ a gravitational force‚ the applied

Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials

Title: A Discussion for Free Trade Introduction: Free trade is a policy that refers to a government does not interfere with international trade by applying tariffs‚ subsidies‚ quotas or other ways. It is a system that capital‚ labor and other resources flow freely between nations without barriers which could hinder the trade process‚ and also do goods‚ services. For a long time‚ free trade plays an important role during the process of the development of world economy‚ especially along with the rapid

Free Fall Methods Investigation Aim I am going to use three different methods in which I will find the value of gravity (g). Then I am going to compare all three methods to see which is the best. The three experiments will be - Pendulum - Spring - Electronic timer Background Research Free fall Is motion with no acceleration other than that provided by gravity‚ and no deceleration other than that caused by the aerodynamic drag of the object (hence the term also applies for moving

ACCELERATION: Good afternoon everyone! Our group will discuss about acceleration. But before that‚ what is acceleration? Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. People will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration

Physics 2111 Student professor Lab #3 Free Fall With Air Resistance The experiments in this lab will demonstrate the relationship between air resistance and acceleration of an object during free fall.To calculate the acceleration you will use the following formula: 2 delta x/ t^2 In this lab you will drop coffee filters from a height of one meter. You will measure their acceleration by measuring the vertical distance and the time that coffee filters take in traveling that distance
