Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

Lab 4: Kepler’s Laws (answer sheet) 1. a: semi-major axis b: semi-minor axis c: focus d: center 2. The distance from the center to a focus is 31 millimeters and the length of the semi-major axis is also in millimeters. The numbers are not even and cannot be simplified any further than what they are since 31 is a prime number. The number is 31/102‚ or 31 divided by 102 which results in 0.303921568627451. 3. Kepler’s first Law is that all planets orbit in an elliptical (egg

Kepler: Scripture vs. Astronomy Johannes Kepler was one of the first natural philosophers that defended the design of the cosmos created by Nicolas Copernicus. Kepler argued that Copernicus’s system of the universe was not only the correct structure that man had been searching for‚ but also that by knowing this‚ he was able to more fully understand the thinking of his Creator. In this paper I will demonstrate how Kepler was able to use Christian theological principles in order to connect the

Astronomy HOMEWORK Chapter 1 9th ed 5. In Figure 1-8‚ what is another name for the “Sun’s annual path?” Ecliptic. This term also refers to the mathematical plane of Earth’s orbit. 10. By about how many degrees does the Sun move along the ecliptic each day? The Sun moves 360 degrees in 365.25 days along the ecliptic‚ so Degrees per day = (360◦ )/365.25 days = 0.986◦ = 1◦ . Round to 1 degree since the question says “about how many...” 14. What are the vernal and autumnal equinoxes? What are the summer
