An object has a mass of 120 kg on the moon. what is the force of gravity acting on the object on the moon?
a. 12.24 n
b. 20 n
c. 1,176 n
d. 196 n user: a man standing on a bus remains still when the bus is at rest. when the bus moves forward and then slows down the man continues moving forward at the original speed. this is an example of the effect of
a. velocity.
b. gravity.
c. weight.
d. inertia.

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^.
