Calculate the PE and KE at top of the hill and at bottom of the hill using trigonometry when needed and include a picture of your calculation in your report. Include a screenshot of your setup when the object is at the bottom of the ramp. Is the total energy the same at the beginning as it is at the end? What is the percent difference? Please show your calculations!

Which articulations allow for greatest range of motion?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
