Gravitational force

In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is…

Acceleration Due to Gravity

In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the othe…

In Fig. 13-32, a square of edge length mị 20.0 cm is formed by four spheres of masses m; = 5.00 g, m, = 3.00 g, m3 = 1.00 g, and m4 = 5.00 g. In unit-vector notation, what is the net gravitational force from them on a central sphere with mass m, = 2.50 g? •7 One dimension.

**68 @ Two small spaceships, each with mass m = 2000 kg, are in the circular Earth orbit of Fig. 13-51, at an altitude h of 400 km. Igor, the commander of one of the ships, arrives at any fixed point in the orbit 90 s ahead of Picard, the commander of the other ship. What are the (a) period To and (b) speed Vo of the ships? At point P in Fig. 13-51, Picard fires an instanta- neous burst in the forward direction, reducing his ship's speed by 1.00%. After this burst, he follows the ellip- tical orbit shown dashed in the fig- ure. What are the (c) kinetic energy and (d) potential energy of his ship immediately after the burst? In Picard's new elliptical orbit, what are (e) the total energy E, (f) the semimajor axis a, and (g) the orbital peripd T? (h) How much earlier than Igor will Picard return to P?
