Question

An artificial satellite goes around the earth in a perfect circular orbit with constant speed . Why? Give reason .

Answer 1

Answer:

acceleration depend on velocity

Explanation:

Speed - is a scalar quantity, which only has magnitude. Velocity - is a vector quantity, it possesses both magnitude and direction. A geostationary satellite orbits the earth with a velocity of 3.07km/s. So, the satellite orbits the earth with a constant speed of 3.07km/s because the magnitude of its speed is constant.

Answer 2

Answer:

Speed - is a scalar quantity, which only has magnitude. Velocity - is a vector quantity, it possesses both magnitude and direction. A geostationary satellite orbits the earth with a velocity of 3.07km/s. So, the satellite orbits the earth with a constant speed of 3.07km/s because the magnitude of its speed is constant
