Gravitational Force is an attraction between two bodies by the virtue of their mass. The force of attraction between two point masses is , where m1 and m2 are the masses of the particles and r is the distance between them. G is a universal constant having the value 6.67 × 10-11 Nm2kg-2. Read More>>
Image of The Week
India's first mission to Mars has captured a stunning new 3D view of a vast chasm, revealing gullies shaped by erosive forces on the Red Planet. The images, sent back by India's Mars Orbiter Mission (MOM), show Ophir Chasma, a portion of the massive Valles Marineris system that stretches across much of the planet's equator. The images were taken July 19 and have a resolution of about 315 feet (96 meters). The new images show the chasm from above and two different views of the sides, revealing hills, small impact craters and gullies shaped by landslides.
