Answer:
1.Objects that are closer together have a stronger force of gravity between them. For example, the moon is closer to Earth than it is to the more massive sun, so the force of gravity is greater between the moon and Earth than between the moon and the sun. That's why the moon circles around Earth rather than the sun.
2.Gravity is a force that pulls objects down toward the ground. When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion.
3.When a ball is thrown upwards its velocity starts decreasing upto the max height that ball can achieve depending on the kinetic energy imparted to it. The speed decreases as the ball goes up because the kinetic energy of ball starts changing to potential energy.
