When we see a question with a casual statement like "a car hits a wall", we reflexively invoke the simplifying assumption that the wall is immovable in order to concentrate on presumably more interesting aspects of the problem. Our assumption is equivalent to assigning an effectively infinite mass to the wall or at least to whatever the is holding the wall in place.Lokendra1799 said:Analysing the Car, there is a large change in momentum of the car (Impulse acts on it) and if we analyse the wall, the initial velocity was zero and the final velocity is also zero..so Impulse must be zero.
Car has more impact than the wall. You are right that the Third law of Newton beholds here. I think the question might be asking about the impact?
Momentum is a measure of an object's motion. It is calculated by multiplying an object's mass by its velocity.
When a car hits a wall, the momentum of the car is transferred to the wall. This is due to the law of conservation of momentum, which states that the total momentum of a closed system remains constant.
Yes, both the mass and velocity of the car affect the momentum. The greater the mass and velocity of the car, the greater the momentum will be.
After the car hits the wall, the momentum of the car is transferred to the wall. The car will then come to a stop, and the wall will experience an equal and opposite force, causing it to move slightly.
Yes, the momentum of a car hitting a wall can be calculated by multiplying the mass of the car by its velocity. However, this assumes that the collision is perfectly elastic, meaning that no energy is lost during the collision.
