Through weeks of learning kinematics, static equilibrium, dealing problems with motion. We’ve moved to focus on momentum. Momentum is how much motion an object has. The equation for momentum is P: MV which M stands for mass and V stands for velocity. Its unit is kg m/s. Furthermore, momentum is a vector as well. We have so many problems related to momentum. To expand this idea, we also have Law of conservation of momentum which is articulate the idea that total momentum will be the same before and after a collision. This law of conservation is true only in a closed system. A closed system is a system where is no external force that acting on an object. Talking about momentum, we shall never forget collision! The collision takes a really main point in momentum. For instance, here are some examples we’ve done:
