# Stem Round 5

Haa! Stem class, it was a really tired and experience from stem class this round, I have learned about Newton laws Of Motion, and Newton laws of motion have three laws in there, the first Newton laws can also call as inertia and it is about Force and Motion. Newton’s first law of motion states that an object’s motion will not change unless an unbalanced force acts on the object. If the object is at rest, it will stay at rest. If the object is in motion, it will stay in motion. Inertia is the tendency of an object to resist a change in its motion. The inertia of an object depends on its mass. Objects with greater mass have greater inertia. To overcome inertia, an unbalanced force must be applied to an object. The second-newton laws of Motion are about Acceleration, Force, and Mass. Newton’s second law of motion states that the acceleration of an object equals the net force acting on the object divided by the object’s mass. Weight is a measure of the force of gravity pulling on an object of a given mass. It equals the mass of the object (in kilograms) times the acceleration due to gravity (9.8 m/s2). The third Newton laws of motion are about Action and Reaction. Newton’s third law of motion states that every action has an equal and opposite reaction. Momentum is a property of a moving object that makes it hard to stop. It equals the object’s mass times its velocity. When action and reaction occur, momentum may be transferred from one object to another, but their combined momentum remains the same. This is the law of conservation of momentum. Moreover, then Newton’s laws, we have learned about Fluid Forces and Work and Machines. Finally, we had an opportunity to do an experiment about Fluid Force with eggs and glass bottles here you can take a look!
