Forces
Question:
Does gravity (the physical force pulling any two bodies with mass together) exist in "Angry Bird" land? Is it the same as Earth's gravity?
Does air resistance (a drag force exerted on an object moving through the air) seem to exist in AB land?
Does air resistance (a drag force exerted on an object moving through the air) seem to exist in AB land?
Answer:
Gravity does exist in Angry Bird Land. It is approximately 6.12 m/s/s, which is different from Earth's gravity, 9.8 m/s/s.
Air resistance does not exist in Angry Bird Land, proved by the fact that the bird's x-component velocity is constant and that its x displacement versus time is a straight line. This would not be the case if there were air resistance; the bird's horizontal velocity would decrease.
