No. The earth's orbit round the sun is elliptical and there are two points Aphelion and Perihelion where it is nearest and furthest from the Sun in Summer and Winter. The orbit is stable and if anything the Earth may be moving very slowly away from the Sun due to tidal energy losses.
because people have a smaller mass than that of earth, they are attracted into earth's gravitational field. Theoretically, Earth is moving closer to the sun every day, so we technically are moving towards the sun.
The moon is moving further away by 1.5cm from the Earth every year.

No. Earth's orbit is stable.
It changes every day
There is no definite speed for free falling. If an object is released somewhere above the earth, the speed is changing every single moment. It is never the same speed it was before at any time; only until an object releases terminal velocity where it is moving at a constant speed. This is different for every object. The acceleration due to the gravity of the earth is 32 feet/second^2. This means that for every second that passes, an object is moving 32 feet/second faster than it was the second before.
Yes, if you're using the co2 car on Earth. All of Newton's laws will affect every moving object on Earth, and your co2 car is no exception.
Acceleration due to gravity is the constant rate at which an object falls towards the Earth, which is approximately 9.81 m/s^2. Uniform accelerated motion refers to an object moving with a constant acceleration, such as a car increasing its speed by a fixed amount every second.
accelerating
Every second of every hour of every day.
It is traveling about 51.3 feet every second.
