(a) Calculate the magnitude of the gravitational force exerted by Venus on a 75 kg human standing on the surfa?
the answers to a and b are the same (Newton's third law) F = G m1 m2/r^2 F = 6.67x10^-11(75kg)(4.91x10^24kg)/(6.1x10^... F= 659N between two people: F = 6.67x10^-1(75kg)(75kg)/(3.5m)^2 = 3x10^-8N gravity is a very weak force...it takes a lot of matter (like aplanet) before we notice the effects of gravity
What is the acceleration due to gravity on the moon?
The acceleration due to gravity on the moon can be calculated using:g = GM/(r^2)Where g is the acceleration due to gravity in m/s2, G is the gravitational constant 6.67 * 10^-11 Nm2 / kg2M is the mass of the moon in kg (7.35 * 10^22)r is the radius of the moon in metres (1737400m)g = (6.67 * 10^-11) * (7.35 * 10^22) / (1737400)^2g = 1.624 m/s2
Determine the magnitude of the gravitational force Mars would exert on man if he was on the surface of Mars.?
Determine the magnitude of the gravitational force Mars would exert on man if he was on the surface of Mars. The mass of the man is 69.0kg . The mass of the Mars is 6.42×1023kg and its radius is 3396 km.
Is the centripetal acceleration of Mars in its orbit around the Sun larger or smaller than the centripetal?
well, the formula is (G*m1*m2)/d^2 so the distance changes the force of gravity which changes the centripetal acceleration mars is larger
How does centripetal acceleration of Mars around the sun compare to the centripetal acceleration of the Earth?
The centripedal force (yes I know it's really inertial force, no need for nit picking) of an orbiting body exacly balances the gravitational force exterted on it. Since Mars is farther from the earth than the sun, the gravitational force acting on it is less. Therefore its centripedal force is equally less.
Does the Sun exert a larger force on the Earth than that exerted on the Sun by the Earth? How would you explain your answer?
The Sun exerts exactly the same amount of force that the Earth exerts on the Sun. This is summed in the equation[math]F = G\frac{M_1M_2}{r^2}[/math]this is the equation that calculates the force between two objects based on their mass, the distance between them, and the gravitational constant.The fact that the two forces are equal are also clearly stated in Newton’s Third Law of Motion, that “For every action, there is an equal and opposite re-action”. Forces always come in pairs, equal and in opposite directions.
