What do you mean by Newton's 1st law and 2nd law of motion?

Newton's First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it, and a body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force. If a body experiences an acceleration ( or deceleration) or a change in direction of motion, it must have an outside force acting on it. Outside forces are sometimes called net forces or unbalanced forces. The property that a body has that resists motion if at rest, or resists speeding or slowing up, if in motion, is called inertia. Inertia is proportional to a body's mass, or the amount of matter that a body has. The more mass a body has, the more inertia it has. The Second Law of Motion states that if an unbalanced force acts on a body, that body will experience acceleration ( or deceleration), that is, a change of speed. One can say that a body at rest is considered to have zero speed, ( a constant speed). So any force that causes a body to move is an unbalanced force. Also, any force, such as friction, or gravity, that causes a body to slow down or speed up, is an unbalanced force. This law can be shown by the following formula F= ma F is the unbalanced force m is the object's mass a is the acceleration that the force causes If the units of force are in newtons, then the units of mass are kilograms and the units of acceleration are m/s2. If the units of force are in pounds (English), then the units of mass are in slugs, and the units of acceleration are ft/s2. Motion of an object that is not accelerated (moving at a constant speed and in a straight line) can be found using the formula d= v t d is the distance traveled v is the rate of motion (velocity) t is the time read less

Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. Moment of Inertia is 2types. Inertia of rest and inertia of motion. Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. So, Force= Mass x Acceleration F= ma read less

Newton's first law indicate to change the momentum of an object you should apply an external force otherwise it will continue its state of rest or uniform motion in both case momentum (mv) is constant. Newton's second law state rate of change of that momentum (ie how fast it occur) is proportional to your applied force (F = mdv/dt =ma) read less
