Slightly greater gravitational force.
Gravity follows the inverse square law, specifically in Newtonian physics we can use the following equation:
Let's focus on the part of the equation which denotes the distance between these two objects. So if the distance is smaller, we will get a larger gravitational force, and if the distance is larger we will get a smaller gravitational force. Therefore, since in December, Earth is slightly closer to the Sun then we would experience a slightly greater gravitational force.

If long sight means farsighted, then here's your answer:
Farsightedness is when the lens has difficulty focusing on nearby objects. Sufferers must squint to see the nearby objects. Reading, writing, and drawing for longer periods of time can cause eyestrain and headache.
Being farsighted can be corrected with prescription glasses or contact lenses or surgery.
It traveled 200 m in 50 seconds. 200/50 can be simplified to 4 m/s!
The velocity is -4 m/s (negative because it travelled from 100 to -100 or backwards)
