Answer:
Gravitational force is the force that attracts objects towards each other. Two factors that affect the gravitational force between objects are the mass of the two objects and the distance between
Explanation:
Gravity is what pulls us towards the Earth if we were to jump into the air, so it is the force that pulls things towards other things. The bigger the objects are the more gravity they have, so a planet has more gravity than say, an apple. Distance between objects also makes their gravity change, so the Earth's pull on the moon is different than the Earth's pull on the sun.

answer = true
reasoning
kinetic energy is the energy of movement
potential energy is built up kinetic energy

Answer:
A. Calculate vector
B. Update vector of each object
C. Update position of each object
Explanation:
Taking assumption of a system in which the forces are a function of the previous step's final position:
Firstly, we calculate the (vector) forces acting on the objects.
Secondly, Update the (vector) momentum of each object
(note: also update the velocity).
Thirdly, Update the (vector) position of each object.
The other operations are as follows;
i. select (dt),
ii. define mass,
iii. Put down constants,
iv. initialize variables, this would occur before the time-step loop is entered.
We can solve the problem by using the mirror equation:

where
f is the focal length

is the distance of the object from the mirror

is the distance of the image from the mirror
For the sign convention, the focal length is taken as negative for a convex mirror:

and the image is behind the mirror, so virtual, therefore its sign is negative as well:

putting the numbers in the mirror equation, we find the distance of the object from the mirror surface:

So, the distance of the object from the mirror is
