...force is indestructible. For the first law says if a body is in motion, and no force act on it, it will continue to move in a straight line, and with a uniform velocity; that is its direction and speed will keep up for ever. For if the body be in motion some force must... | |

Newton's first law states that a body at rest will remain at rest and a body in motion will move at a constant speed in a straight line unless acted , upon by a force . a.
