1. moto circolare uniforme

2. Motion of a body (CORPO) travelling at a constant speed (VELOCITA’) in a circular path (TRAIETTORIA) r is the radius (RAGGIO) of the path

5. The velocity (v) of a body in UCM is variable and is tangential (TANGENTE) to the path of motion This is the reason why in UCM we have an acceleration

8. The Earth (TERRA) orbits the Sun (SOLE) once a year (ANNO) (3.16x10 7 s) in a nearly circular orbit of radius 1.50x10 11 m. With respect to the Sun, determine: a) the angular velocity of the Earth b) the speed of the Earth c) the magnitude and direction of the Earth’s centripetal acceleration
