My answer is infinity.
Newton's three laws of motion are: 1) An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force. 2) The force applied to an object is equal to its mass multiplied by its acceleration. 3) For every action, there is an equal and opposite reaction.
Newton's laws of motion apply to everyday life in many ways. For example, the first law explains why objects keep moving or stay still unless something acts on them. The second law can be seen in the way objects accelerate or decelerate when a force is applied. The third law is evident in actions such as pushing off the ground to walk or jump, or even in the recoil of a gun after firing a bullet.
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. According to Newton's second law, weight is directly proportional to mass, meaning that an object with a greater mass will experience a greater force of gravity. However, the amount of matter in an object (its mass) remains constant regardless of gravity or location, whereas weight can change depending on the strength of gravity.
Newton's first law, also known as the law of inertia, states that objects will remain in their state of motion unless acted upon by an external force. This means that objects with more mass (greater inertia) will require a greater force to change their motion. In other words, the more mass an object has, the more resistance it has to changes in its motion.
Yes, Newton's laws of motion can be applied to objects in space. In fact, these laws were originally developed to explain the motion of celestial bodies such as planets and moons. The laws still hold true in the vacuum of space, where there is no friction or air resistance to affect the motion of objects.
