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

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

This instrument‚ which makes far-away objects more visible has facilitated both learning about and understanding our universe. This paper will discuss the importance of telescopes‚ their three major designs‚ and the strengths and weaknesses of different locations for telescopes. In addition‚ this paper will discuss the frequencies of light and the

Radio Astronomy Essay In the 1930s a huge discovery was made; one that has led to many subsequent discoveries about the world beyond Earth. This discovery was radio astronomy‚ the study of celestial objects at radio frequencies. Radio and optical astronomy are two different ways to study stars‚ planets and moons in the universe; but the most useful would have to be radio astronomy. Despite this‚ there are some who do argue that optical astronomy is the more useful of the two. Radio waves are a form
