  1. Gravity and Its Effects Gravity is the attraction between two particles due to their mass. *The force of gravity depends on the mass of the two objects. The larger the mass- the bigger the effect. *You will not notice the gravitational affect of your friend sitting next to you, but can feel the affect of the earth on your body. Why? *Gravity also depends upon the distance between two objects. The closer together they are, the larger the affect of gravity.

  2. Which situation has the greatest amount of gravitational attraction? Which situation ) has the least amount of gravitational attraction? C A D B

  3. Add mini-break wtih ranking items graviitational forces

  4. The force of an object being pulled on by gravity is called weight. *When you get on a scale, you are measuring your weight. *Our weight depends on the gravity we are in, while our mass (the measure of how much matter you're made of) is always the same. We use the formula of weight equals mass times acceleration due to gravity to calculate weight. *In this formula, mass has to be in kilograms (kg) and acceleration is in m/s2. *The weight will be measured in Newtons, which are the units we use to measure forces. (FYI- the english system uses pounds to measure weight!) Weight W=m·g Weight (N)= mass (kg) x acceleration from gravity (m/s2)

  5. Practice: 1. A bag of sugar has a mass of 2.6 kilograms. What is its weight on Earth? 2. Your weight is 620 N, what is your mass? 3. Explain why Venus, which is slightly less massive than Earth, experiences a greater gravitational pull from the Sun than the Earth does. 4. Explain why the statement “There is no gravity in space” is untrue.
