An earth satellite in an elliptial orbit moves with
a) slower speed as it ages
b) none of the above
c) constant speed
d) faster speed as it ages
Just need to know if my answer or right or wrong. Thanks! :)
b or d but im strongly going for D but i could be wrong
b is correct.
thanks bobpursley :)
To determine the correct answer, let's analyze the motion of an earth satellite in an elliptical orbit.
An elliptical orbit is an oval-shaped path followed by a satellite around the Earth. In an elliptical orbit, the satellite moves at varying speeds at different points along its path.
As the satellite moves closer to the Earth during its orbit, it experiences a stronger gravitational pull, which causes it to speed up. This is due to the conservation of angular momentum, which means that as the satellite gets closer to the Earth, it balances the decrease in altitude with an increase in speed to maintain a constant angular momentum.
On the other hand, as the satellite moves farther away from the Earth during its orbit, the gravitational pull weakens, causing the satellite to slow down.
Therefore, the correct answer is:
d) The satellite moves faster as it ages when it is closer to the Earth and slower as it moves farther away.
So your choice of d) is indeed correct! Well done!
