How long will it take a ball to fall 81 feet
A planet has ? the density of earth but 2x the radius. find the surface gravitational force on this planet. (Hint: Earthâ€™s is 10N/Kg)
Jupiter has a mass of 1.90 x 1027 kg. the semi-major axis of its orbit is 7.78 x 1011. Th radius of the planet is 7.14 x 107 m. Io, one of jupiter's moons, orbits at a distance...
I was thinking about gravity and isn't it a meters per second per second per second acceleratory force? I mean, as you get close to an object's center of mass the force of gravity gets stronger,...
A ramp is inclined at 12 degrees to the horizontal. A cart is pulled 8m up the ramp by a force of 120N, at an angle of 10 degrees to the surface of the ramp. Determine the mechanical work done against...
