Step-by-Step Solution:
Step 1 of 3
Solution 2P
Newton's first, second, and third law can be expressed as follows.
Newton’s first law states that a body at rest remains at rest, and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero. Therefore, a body tends to preserve its state of inertia.
Newton’s second law states that the acceleration of a body is proportional to the net force acting on it and is inversely proportional to its mass. For a rigid body of mass , Newton’s second law is expressed as
Where is the net force acting on the body and
is the acceleration of the body under the influence of
.
Newton’s second law can be also be expressed as =
