Conclusion

In conclusion, this experiment was conducted to discover the gravity, projectile motion, orbital velocity of a satellite and escape velocity of an object on two planets which had different mass and radius. The gravity of Planet A was calculated as and was bigger than gravity of Planet B , because of this distance which flew projectile was smaller than on Planet B. The reason is that because gravity on the Planet A more than on the Planet B. This is based on the fact that Planet A had a bigger than Planet B’s mass. The mass of a Planet A that was given is three times bigger than Planet B and radius is smaller than radius of Planet B, caused of this velocity of satellite around Planet A , while around Planet B velocity was , it means that satellite should have bigger velocity to stay on planet’s orbit. Therefore, gravitational pull of Planet A is much bigger than on Planet B. On part “Escape Velocity of an object” masses and radiuses of the planets played a considerable influence on the final results. Results shows that, to overcome the force of attraction of the Planet A, the object should have to type a minimum velocity which is equal to , while for Planet B minimum velocity should be , because Planet A has bigger gravitational pull than Planet B.
