physics

• Newton‘s first law states that an object will remain at rest or in uniformed motion unless acted upon by a resultant force
• Newton’s second law states that the acceleration of an object is directly proportional to the resultant force applied to it. The mass is a constant of the proportionality
• Newton‘s third law states that if body A exerts a force on body B, body B will exert an equal and opposite force on body A
• Inertia is the measure of reluctance of a body to change its state of motion
