hypothesis - ANSWERSAn idea that is based on evidence but requires further testing



observation - ANSWERSTest of an idea by taking data from an environment in nature



experiment - ANSWERSTest of an idea by taking data in a controlled setting such as a laboratory



opinion - ANSWERSA belief that may or may not be backed by evidence



Perform a carefully controlled observation or experiment - ANSWERSSuppose a friend tells you that hot
water freezes faster than cold water but you are skeptical of this claim. According to the Scientific
Process, what is the best way to determine whether the claim is true?



b & e - ANSWERSIf I am standing on a table and the table is holding me steady, which of the following
statements are true? Choose all that apply



a) The normal force on me is stronger than the gravitational force on me.

b) There is no net force on me.

c) There are no forces on me at all.

d) The gravitational force on me is stronger than the normal force on me.

e) The normal force is equally strong as my weight.



The Sun and Jupiter exert equal forces on one another but in opposite directions - ANSWERSThe Sun is
more massive than the Jupiter. Which of the following is true about their gravitational interaction



false - ANSWERSA 5,000,000 kg asteroid flying through space at 10 m/s has more momentum than an

, The astronaut is both in orbit and in freefall - ANSWERSSuppose an astronaut is floating in the
International Space Station, which is orbiting the Earth. Which of the following is true?



I would be falling through the ground - ANSWERSIf the ground pushed me upward with a normal force

tennis ball - ANSWERSSuppose a moving car hits a flying tennis ball. Which object accelerates more?



true - ANSWERSBecause Mars has a smaller acceleration due to gravity than Earth, I would weigh less on
Mars than on Earth



neither - ANSWERSSuppose a moving car hits a flying tennis ball. Which object exerts a stronger force on
the other?



not at all - ANSWERSSuppose a space ship is flying through space. It is subjected to a force of 50 N
leftward and 50 N rightward at the same time. In what way will it accelerate?



c - ANSWERSWhich will accelerate more?



a) A 10,000 kg cart being pushed with 100 N of force

b) Neither
