In the context of flight, which force acts in the direction opposite to the $\mathrm{thrust}$ force and counteracts it?

According to Newton's Law of Gravity ($F=\frac{\mathrm{Gm\_1m\_2}}{r^2}$) and the forces acting on a falling object, when does a skydiver achieve terminal velocity?

Given that the Moon's mass is $7.4\times {10}^{22}$ kg and it orbits the Earth at a distance of $3.8\times {10}^8$ m with a period of 27.3 days, which of the following expressions correctly gives the mass of the Earth according to Newton's Law of Gravity and circular motion?

Which of the following is primarily responsible for causing a bullet to spin as it is fired from a gun?

According to Newton's Law of Gravity, which two factors determine the magnitude of the gravitational force between two objects?

According to Newton's Law of Gravity, how do the mass of the Sun and the distance between the Sun and the Earth affect the length of one year (the orbital period of the Earth)? $T=\sqrt{\frac{4{\pi }^2{r}^3}{GM}}$ where $T$ is the orbital period, $r$ is the distance between the Sun and the Earth, $M$ is the mass of the Sun, and $G$ is the gravitational constant.

According to Newton's Law of Gravity, what would most likely happen to the Earth and Moon system if the Sun suddenly ceased to exist?
