1.A rock that is lying on the ground will continue to so for thousands of years unless it is pushed by nature or by some force. It won't be floating around in different places.
2.In a game of baseball,a baseball is hit by a bat. The muscular force is transfer to the ball via the bat which changes the direction and speed of motion of the ball.
3.In outer space,there is not much effect of gravity for human. But larger objects like planets experience gravitational force from the sun. This is a force that keeps the solar system in place.
4.We can float in water without moving for a long time. But for motion,we need to apply muscular force by our hands and legs to push the water backward and propel ahead.
5.A rolling ball should roll forever according to Newton's First Law of Motions. But the external force of rolling friction stops it from rolling forever.
