Problem 17
What is Newton's universal law of gravitation? Write it in equation form, and clearly explain what the equation tells us. What do we mean when we say that the law is an inverse square law?
Problem 18
How did Einstein's general theory of relativity change our view of gravity? Why do we say that Newton's law of universal gravitation is still a valid approximation to Einstein's theory of gravity?
Problem 19
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.David Beckham was the best soccer player of his generation.
Problem 20
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.Several kilometers below its surface, Europa has an ocean of liquid water.
Problem 21
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer. My house is haunted by ghosts, who make the creaking noises hear each night.
Problem 22
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.There is no liquid water on the surface of Venus today.
Problem 23
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.Bacteria from Earth can survive on Mars.
Problem 25
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.Aliens can manipulate time so that they can abduct people and perform experiments on them without the people ever realizing they were taken.
Problem 26
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.Newton's law of gravity explains the orbits of planets around other stars just as well as it explains the orbits of planets in our own solar system.
Problem 27
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.God created the laws of motion that were discovered by Newton.
