| A | B |
|---|
| What is the only object in your life whose gravity you can feel? | Earth (duh!) |
| If we drop something here on Earth, where is it attracted to? | The center of the Earth |
| Does the Moon have gravity? | Yes, 1/6th of Earth's |
| Does the Moon have an atmosphere? | No, black sky! |
| Why does wadded up fall faster than flast paper? | Wadded up paper catches less air |
| How fast do things accelerate (speed up) as they fall toward Earth? | 9.8 m/s/s |
| How fast will a falling object be going after 3 seconds of free fall? | 29.4 m/s (3 x 9.8 m/s/s) |
| Do parachutists accelerate forver? | No |
| What do you call the final speed that falling objects like parachutists reach? | Terminal Velocity |
| Why would a parachute be useless on the Moon? | Moon has no air |
| When we removed air from the tube, which fell faster, the feather or the penny? | They fell the same (no air resistance) |
| Who is given credit with proving mass does not affect rate of fall? | Galileo at the Leaning Tower |
| What happens to the weight and mass of falling objects? | Mass is constant, Weight = 0 |
| What did David Scott drop on the Moon to show all objects fall the same where there is no air? | Hammer and feather |
| Why do I feel Earth's gravity more than the Sun's if the Sun is a gazillion times bigger? | I am closer to the Earth |
| When do falling objects quit accelerating? | When the pull of gravity is equal to the air resistance |
| Why does Mars' moon Phobos have so little gravity? | It is VERY small (dinky) |
