What do we call a projectile that continually 'falls' around Earth?
A projectile that continually falls around the Earth.
Explanation of Solution
Introduction:
An object that revolves around another object is called a satellite. There are two types of satellites. Natural satellites like the moon and artificial satellites like ISS, HST, etc.
An artificial satellite is projected into space with a certain orbital velocity which puts the satellite into a fixed orbit around the Earth. The only force acting on the satellite is the Earth’s gravity. A projectile is an object which is thrown into space with some force and freely moves under the influence of gravity.
Conclusion:
Thus, a satellite is a project which continually moves around the Earth and can be said to be in free fall because only gravitational force acts on it.
