Question
If a two-body collision is not head-on, then we may always assume that:Select one:a.both momentum and kinetic energy are conserved.b.neither momentum nor kinetic energy are conserved.c.momentum is conserved.d.kinetic energy is conserved.
Solution
In a two-body collision that is not head-on, we can always assume that momentum is conserved. This is a fundamental principle of physics, known as the law of conservation of momentum. It states that the total momentum of a system of objects is constant, if no external forces are acting on it.
However, kinetic energy is not always conserved in these collisions. This is because some of the kinetic energy may be converted into other forms of energy, such as potential energy or thermal energy, during the collision.
So, the correct answer is c. momentum is conserved.
