(1 point) The acceleration due to gravity, g, is given by 8= GM r2 where M is the mass of the Earth, r is the distance from the center of the Earth, and G is the uniform gravitational constant. (a) Suppose that we increase from our distance from the center of the Earth by a distance Ar = x. Use a linear approximation to find an approximation to the resulting change in g, as a fraction of the original acceleration:...
An object of mass m moves at a constant speed v in a circular path of radius r.
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...

please help with question 4.
EXPERIMENT4: THE LINEAR AIR TRACK The aims of this experiment are to: 1)investigate momentum and energy conservation in coll 2. study the cooversion of energy for a body in free fall. There are two types of collisions, elastic and inelastic. In both types of collision momentum is between two bodies in one dimension. The velocity (and hemee the momentum) may be positive or ycorserved. A body of mass m moving with a velocity vi has...
