Gravitational force depends only on an object's mass and its distance from the center of the earth.
Its speed has no effect on the gravitational force.
increases with speed
As an object approaches the sun, its orbital speed increases due to the stronger gravitational pull from the sun. This increase in speed allows the object to maintain its orbit despite the stronger gravitational force it experiences closer to the sun.
the gravitational force attract all the thing to earth, the force increases 9.81 per second, which is called as gravitional acceleration.( speed is never increases or de creases and unit is m/s, its constant through specify distance and when the speed increases or decreases its called as acceleration its unit is m/s2).
Gravitational Force
As an object gets closer to the object it's orbiting, the gravitational pull between the two objects increases. This causes the object in orbit to accelerate, increasing its speed to balance the gravitational force and maintain its orbit.
The word "falling" implies there is a gravitational force also. As the object gains speed, the air resistance ("drag") increases, until it equals the gravitational force. After that there is no net (resultant) force, so the object goes at constant speed.
The relationship between speed and the force of impact is typically a linear relationship, meaning that as speed increases, the force of impact also increases proportionally. This relationship is described by the kinetic energy formula, where kinetic energy (and therefore force of impact) increases with the square of the speed.
The two main factors that affect escape speed are the mass of the object and the gravitational force pulling it. A larger mass or a stronger gravitational force will result in a higher escape speed required to break free from the object's gravitational pull.

Any Speed above 1,125 is considered Supersonic. There are several pellet rifles capable of this speed. As an example the PCP Air rifle, Air Force Condor is capable of firing a .177 pellet at 1,450 FPS.
As the ramp angle increases, the force of gravity pulling the toy car down the ramp also increases. This increased gravitational force provides more acceleration to the toy car, causing it to speed up. Additionally, the steeper angle reduces the amount of friction between the toy car and the ramp, further contributing to the increase in speed.
Speed has nothing to do with where you are. You can travel at supersonic speed pretty much anywhere if you have the right vehicle.
