An explosion can be thought of as a single object separating into two or more fragments. In this post, we will see if the law of conservation of momentum is maintained during an explosion. We will solve related numerical problems as well. Some familiar examples of explosions are: a bomb blowing into fragments a bullet […]
Numerical problems on collisions of objects in two dimensions. We will solve the collision problems using axial-vector components and the law of conservation of momentum.
How do rockets work? As the rocket engines operate, some kind of fuel (liquid or solid) is burnt. The engines continuously eject burned fuel gases. As these exhaust gases have both mass and velocity, they have some momentum as well. By the principle of conservation of momentum, the rocket’s momentum changes by this same amount […]
