As the data is representative of a graphical parabola, a parabolic function was utilized to be the best fit trendline. There are many properties that distinguish an ionic compound from a covalent compound. In experimental situations the numbers will not come out to be exactly perfect, but if the ration of the momentums is close to one it will indicate that momentum has been conserved. - Explore the relationship between kinetic and gravitational energies, The m is the mass of the object and v is the velocity of the object in motion. As the height decreases the GPE will decrease while its kinetic energy ____________. This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. : an American History - Chapters 1-5 summaries; Analysis of meaning and relevance of History from the millennial point of view; Newest.
