Force = G times (m1 x m2)/r^2
If you double the masses your have 4 times the force. since the distance is the same and the "G" is a constant.
you lift a 10 N physics book up in the air a distance of 1m at a constant velocity of .5m/s. What is the work done by the weight of the book? a) +10 J b)-10 J c) +5 J d)-5 J 10 N is the force of gravity and to find work you do this: W=F_g(change in
A 5.0 kg book is sitting on a table. Which describes the force acting on the book a. there are no forces acting on the book b. the force of the table upward is greater than the force of gravity downward c. the net force on the book is zero d. kinetic
The weight of an object is the same on two different planets. The mass of planet A is only forty-five percent that of planet B. Find the ratio rA/rB of the radii of the planets.
Two rocks of very different sizes are dropped from the same height. Which value will be different for the two rocks?(1 point) the acceleration of the rocks the velocity of the rocks after a few seconds the downward pull of gravity on the rocks the time it
THree blocks of masses 3m, 2m and m are connected to strings A,B, and C. The blocks are pulled along a rough surface by a force of magnitude F exerted by string C. The coefficient of friction between each block and the surface is the same. Which string
1.) Why was the geocentric model accepted for more than a thousand years?(1 point) > It correctly explained the distribution of the stars. > It was confirmed by astronomers using telescopes. > It correctly described the solar system. > It correctly
2.)which of the following statements about the solar system's formation is true? a:the temperature was very cold. b:gravity pulled together a cloud of gas and dust. c:objects formed from the same materials. d:the planets formed at the same distance from
Newtons 2nd law The force of earths gravity is about 10 N downward. Whats the acceleration of a 15kg backpack if lifted with a 15N force??
In a drawing that represents a scale model of the solar system, the sun is placed at the center and the planets are shown orbiting in circles around it. While in reality Mars is 1.5 AU away from the sun, in the model Mars appears at 30 cm from it. Neptune
two planets of masses "m" and "M" respectively. have a center to center separation of "R".At what distance from the center of the planet of mass"M" do the gravitational force of planets cancel each other????? help me plzzz??????
