No, there is no gravity gradient.
Though it could be if it was somehow mounted in a centrifuge.
No. Other stars have been found to have planets orbiting them.
All the time. (The moon is actually orbiting around the Earth, which is orbiting around the sun)
The first spaceship was made in 1957 with the launch of Sputnik 1 by the Soviet Union. It was the first artificial satellite to be put into orbit around the Earth.
The force of gravity causes the moon to orbit the Earth, and the Earth to orbit the sun.

Ceiling fan, Ferris wheel, the earth spinning around it's axis!
Some science examples of motion include a sliding block on a table, a pendulum swinging back and forth, a planet orbiting around a star, and a car moving along a highway.
Examples of objects that move in circular motion include a yo-yo being swung in a circle, a planet orbiting around a star, a swinging pendulum, and a car negotiating a roundabout.
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
It varies greatly. It will depend on how far away it is from the object it's orbiting. If it is in a circular orbit around the Earth, its speed can be calculated by the formula: speed = Squareroot(398600/(6371+altitude)) This will give you an answer in kilometers per second.

The Knowledge regarding laws of pendulum started from Galileo around 1600 A.D.
A flexible measuring tape can be used to measure the circumference of a pendulum bob. Wrap the measuring tape snugly around the pendulum bob to determine its circumference. Alternatively, a string can be used to measure the circumference and then measured against a fixed ruler or measuring tape.
No, there are not.
The large lump of rock orbiting around the earth is called the moon
The effective length of a seconds pendulum is typically around 0.994 meters or about 994 millimeters. This length allows the pendulum to complete one full swing in two seconds, which is why it is called a "seconds pendulum."
