# Physics(final)

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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
