Pictures and information of commonly used gadgets or devices which are based on newton first and second law of motion

Answer 1

Isaac Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by unbalanced force. In other words, if no force acts on an object it will maintain a constant velocity (for an object at rest that velocity is equal to zero). With the first law of motion, Newton established the existence of a frame of reference for which his other laws of motion are applicable, called the inertial frame of reference. An inertial frame of reference is one in which the observer is moving at constant velocity (which includes being stationary).

Newton's first law of motion predicts the behavior of objects for which all existing forces are balanced. The first law - sometimes referred to as the law of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not accelerate. According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.
