For two objects in space with very different masses, the gravitational force causes:
A. a force that makes the less-massive object orbit the more-
massive one.
B. a force that makes the more-massive object orbit the less-massive
one.
C. no net force since the equal but opposite forces cancel each other
out.
D. a force in a constant direction that acts only on the larger of the
two masses.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?
