Acceleration is the speed that an object gains with in a short period of time. In the language of Mechanics, Acceleration is the change in the velocities of the objects with respect to the time. So when a ball is thrown up in the air, there will be some acceleration and there will be some speed that the ball will gain when thrown up.

Velocity is the speed of an object but in a particular direction. Velocity of an object is the rate of change of the position of the object with respect to the frame of reference of that frame. So the velocity of the ball up in the air is zero.

4. The north star also called the Polaris star seems to change its position for the southern hemisphere, but as for the northern hemisphere, it remains the same as being the north star the equatorial belt the star remains or shows the same side. Due to the rotation and axial tilt of the earth.

5. The cause of sunrise and sunset is mainly due to the sun and the earth's movement around the horizon in the opposite direction and there is 12 hours gap.
