  • MASS - 1101 Words
    MASS 10/8/14 The Path to Salvation What is Mass the Latin word “missa”. Mass said in Latin, ends in “Ite missa est” meaning “Go, it (the church) is sent”. Through the Mass, we come to know God-Jesus invites us to Himself, then we are dismissed to be Christ for the world. For Catholics, participating and celebrating Mass is a pathway to salvation because it was revealed specifically by Jesus at the Last Supper. What is Liturgy? The Mass is referred to as the “Divine Liturgy”, meaning God’s...

  • Conservation of Mass - 526 Words
     Objective: The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes, which means that no matter how dramatic of a change that a substance goes through, it will not lose mass. It may seem like it lost mass, and usually, if you weighed the result, it...

  • Body Mass - 373 Words
    Body Mass Index MAT221: Introduction to Algebra Body Mass index is a formula that determines the mass of body fat a person has. This formula is used to determine your weight proportion compared to your height if you’re on target, overweight or obese. Today we will use the formula by plugging in my own personal information and determining if I am over weight, on target or obese. To start I plug in the formula BMI=703w/h2. W = weight, H = height. I am 5foot 5 so in the formula my height...

    Open-ended Investigation (mass and force) Aim: To show the relationship between Mass, the force 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...

    While the bob is moving in the circular motion, the centripetal force that is provided is the spring. The spring causes the bob to get pulled inward and while it is being pulled inward while being rotated it provides a centripetal force. If this force was suddenly removed, the Bob would still have a centripetal force due to the rope in which it hangs from causing the inward force to keep moving in a circle. But if the forces are removed than its inertia would keep it moving in a straight line at...
