free from the motion of earth
They both involve gravity calculations
İf gravity is high, satellite will be very small due to lifting forces for satellite,otherw mise satellite wll vey big.
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
A simple pendulum will not swing when it's aboard a satellite in orbit. While in orbit, the satellite and everything in it are falling, which produces a state of apparent zero gravity, and pendula don't swing without gravity.
The force of gravity will change the satellites direction, and therefore its velocity.
They both involve gravity calculations
It certainly gets pulled toward the Earth. Without the pull of gravity, the satellite would continue moving in a straight line, instead of going around the Earth in a circle or ellipse.
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
The path of a projectile in earth gravity is that of a parabola.
No, gravity is only one of the vectors in projectile motion.
Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
Gravity would be pulling down on a projectile object.
In a perfect system, with no air resistance, the arc that a projectile moves through is a parabola. The shape of the parabola is dependent of various parameters including the initial velocity (speed and angle of launch) as well as the prevailing gravity. It could also describe a circle if the launch criteria are just right for the gravity, such as a satellite orbiting the Earth.
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.

Yes, the projectile needs to be accelerated to overcome the acceleration of gravity.
Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.
