| Question | Answer |
|---|---|
| AFter reaching terminal velocity, a hollow tennis ball experiences a greater force of air resistance in fall than does a lead ball of equal size | false |
| a 300kg bear sliding down a tree at constant acceleration experiences no net force | false |
| on a planet where there is no atmosphere, terminal velocity cannot exist. | true |
| if your weight on earth is -600N, then it is about -100 N on the moon | True |
| one kilogram weights 2.2 pounds on earth but not on the moon | True |
| Terminal velocity is greater in the upper atmosphere that it is in the thicker, lower atmosphere | True |
| If your mass is 60 kg on Earth, then your mass on the moon is about 10 kg | false |
| The net force on a ball tossed in the air is zero when it is at the top of its arc, at zero velocity. | False |
| a 60kg skydiver accelerates at about -7.5m/s^2 when the force of air resistance is equal to 150N | True |
| The force of friction due to air resistance is directly proportional to the square of the velocity | True |
| The net force of an F-14D experiences on a catapult-assisted carrier launch is typically about half of the thrust that the engines can produce on their own | false |
| a rocket that loses mass as it rises (due to loss of fuel weight) must also experience a greater and greater acceleration with time if its thrust remains the same. | True |
