Here is information on making an "Act of Spiritual Communion" Sunday on MeTV (over-the-air channel 10.2 and Cable channel 1245). Tom Mull is available on TV - WHEC-TV (Rochester) Forįurther information, consult your state's handbook of Science Safety.Here is a link to our new YouTube channel where you can find our livestreaming Mass each Sunday at 10:15 a.m. Materials used in a project is the sole responsibility of each individual.

This is why you don't get pulled by your friends' gravity enough to get stuck to them! For most things, the masses are so small that the force of attracted is also very small. The universal gravitation constant gives the relation between the two masses and the distance between them. Sir Isaac Newton’s Law of Universal Gravitation states that all masses in universe are attracted to each other in a way that is directly proportional to their masses. The mass of the Earth is 5.97 x 10 24 kg. The sidereal period of the moon, which is 27.3 days, will give you a calculation of Earth's mass that's more accurate than the calendar period of the moon. R is the average distance between the moon and the EarthĪnd G is the universal gravitation constant. Where M e is the mass of the Earth, in kilograms, Why are they different? Which is a more accurate calculation and why? Calculate the mass of the Earth using both the calendar period of the moon and the sidereal period of the moon.R is the average distance between the moon and the Earth, taken as 3.844 x 10 8 m,Īnd T is the orbital period, with units of seconds. Where v is the average velocity of the moon, Use the following equation to calculate the average velocity of the Moon.Do some research on the internet to find the sidereal period of the moon. Use a calendar to determine how long it takes for the moon to orbit the Earth.The time period of an orbit, which you will use in your calculations in this exercise, will have a great effect on the outcome of your answers. The sidereal time of one spin of the Earth is 23 hours and 56 minutes, rather than a round 24 hours. The sidereal period is a number used by astronomers to give a more accurate description of time. An example of this would be the Earth has an orbital period of 365 days around the sun. Orbits, like that of the moon, have what is called a calendar period, which is a round number for simplicity. It can be used to calculate the mass of either one of the bodies if the forces are known, or can use used to calculate speeds or distances of orbits. This is used to calculate the force of gravity between two bodies. Where a Newton, N, is a unit of force and equal to 1 kg*m/s 2. ![]()
