SPACEWALK2INTRODUCTIONA spacewalk also known as an extravehicular activity refers to the phenomenon where astronauts get out of a vehicle in space. Astronauts do spacewalk because of various reasons suchas to carry out experiment in space, to test new equipment and to repair or do routine maintenance on space equipment. This paper discusses the challenges experienced by astronautsin spacewalk to remove and replace a massive satellite component in relation to the three Newton’s laws of motion. The astronaut should always be careful considering the fact that the space conditions are not similar to the normal atmospheric conditions[ CITATION Jam1311 \l 1033 ].Motion has been a topic of interest among scientists, researchers and philosophers. Aristotle, Galileo and Isaac Newton are the key individuals whose ideas helped to shape people’sperspective on motion. Newton’s Laws of motion have been proved and accepted and applied by most people[ CITATION Kue15 \l 1033 ]. Isaac Newton came up with 3 basic laws that describe motion. Newton’s first law of motion states that an object remains at rest or uniform motion in a straight line unless acted upon by an external force. The second law talks about acceleration it states that the acceleration of an object is directly proportional to the magnitude of the resultant force and inversely proportional to the mass of the object and in the same direction as the resultant force. The third law states that for every action, there is an equal reaction force acting inthe opposite direction. These three laws have been used to explain various day to day phenomenon spacewalk being one of them. The Newton’s first law of motion is the principle that keeps planets orbiting round the sun .In the weightlessness space this law is clearly exhibited and the astronaut must be careful. For instance, if the large component being fixed is put down, the object will float out of reach
