The graph represents the gravitational attraction between two equal masses vs. their distance apart, which statement best describes the information presented by the graph?
a) distance is only a factor in space, not on earth.
b) gravitational attraction is directly proportional to distance.
c) gravitational attraction is inversely proportional to distance.
d) gravitational attraction is not related to the distance between objects.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.

Am i correct on these two physics questions?
