How does momentum factor into the force applied to an object at rest hit by another which is moving?
No, its energy. There is an engineering test called a http://www2.umist.ac.uk/material/research/intmic/features/charpy/notes.htm that takes into account all the factors that Halls mentioned and calls the energy required to break a sample "impact toughness". By using a heavy pendulum to break a test sample, the energy required to break it can be measured simply by using the difference in the height of the pendulum between the upstroke and the downstroke and applying the potential energy equation.cscott said:Lets say I have a human bone, and I'm putting weights on it until it snaps, then I have another bone but let the weights fall onto the bone. I'm assuming the second bone will break with less weight because we're letting the weights fall. It is momentum that's involved here? What equations would I be working with?
Momentum is a measure of the quantity of motion that an object has. It is calculated by multiplying an object's mass by its velocity.
According to Newton's Second Law of Motion, the force applied to an object is directly proportional to its mass and acceleration. Momentum is directly related to an object's mass and velocity, so it plays a crucial role in determining the force applied to an object at rest.
Yes, momentum can be transferred between objects through collisions or interactions. In a closed system, the total momentum remains constant, but it can be redistributed among the objects involved.
Momentum affects the motion of an object by determining how much force is needed to change its velocity. The greater the momentum, the more force is required to change the object's motion.
Some examples of momentum in action include a car crash, where the momentum of the moving car causes damage to the stationary object, and a rocket launch, where the momentum of the rocket propels it into space. Sports such as football and hockey also involve momentum, as players use their momentum to gain speed and power in their movements.
