QuestionAnswer
What is the Universal Law of Gravitation? Also what is the equation that goes along with it? Equation: Fg=G m1m2/r2 The Law of Universal Gravitation explains that gravitational force decreases with distance.That the greater an object's mass, the greater its gravitational force.
Why doesn't the moon hit the earth even though it is falling toward it? The earth acts like a centripetal force, pulling the motion of the moon into a circle.
What is centripetal force? A centripetal force is a force is a force that makes a body follow a curved path.
Explain how does the Universal Law of Gravitation effect all objects? Because all objects attract each other. Each object exerts its own gravitational pull.
use the equation of the Law of Universal Gravitation and explain how gravity changes with distance Determine the force of gravitational attraction between the earth (m=5.98 x 10^24 kg) and a 100-kg football player if the player is standing at the earth's surface (sea level), a distance of 6.38 x 10^6 m from each earth's center.
describe and then compare and contrast rotation and revolution Revolution is the motion of one body around another Rotation is the circular movement of an object around the center it helps us keep time.

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:
