Momentum is traditionally used with Newtonian thinking in the conservation of energy, witness the desk toy with the 5 steel balls suspended by threads that cycle back and forth. Momentum here is based on simply equilibroum of the product of mass and velocity.
On the Einstein relativity thinking, applicable to motions of objects approaching the speed of light, the laws of Newtonian logic fall apart, and one has to consider energy, mass and time. Here, momentum does not translate into velocity but rather distortions in time and mass.
What else can I help you with?
Is momentum conserved in elastic collisions?
Yes, momentum is conserved in elastic collisions. This means that the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.
How is momentum affected by collisions?
In collisions, momentum is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision, unless external forces are involved. The distribution of momentum among the objects may change, but the total momentum remains the same.
What is the equasion used to determine the momentum of an object?
Momentum = (mass) multiplied by (speed)
1 In a collision that is inelastic the total what after the collision is not the same as before the collision?
Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.
What is the formula used to determine momentum?
p=mv
Compare and contrast elastic and inelastic collisions?
In elastic collisions, kinetic energy and momentum are conserved, meaning the total energy and momentum before and after the collision are the same. In inelastic collisions, kinetic energy is not conserved, and some of the kinetic energy is transformed into other forms of energy, such as thermal or sound energy. In both types of collisions, momentum is conserved.
What is conserved during collisions?
Momentum and energy are conserved during collisions. Momentum is the product of an object's mass and velocity, while energy is the capacity to do work. In an isolated system, the total momentum and total energy before and after a collision will remain constant.
Is momentum conserved in inelastic collisions?
In inelastic collisions, momentum is not conserved. This is because some of the kinetic energy is transformed into other forms of energy, such as heat or sound, during the collision.
Does momentum conserved during collisions?
Yes, momentum is conserved during collisions. This means that the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision, as long as no external forces are acting on the system.
How is momentum and kinetic energy conserved in elastic collisions?
In elastic collisions, momentum and kinetic energy are conserved. This means that the total momentum and total kinetic energy of the system before the collision is equal to the total momentum and total kinetic energy after the collision. This conservation principle helps to explain how objects interact and move in a predictable manner during elastic collisions.
What is the triangle in impulse and momentum?
The triangle in impulse-momentum is a graphical representation used to calculate impulse, momentum, and force in a physics problem. It shows the relationship between force, time, impulse, and momentum in a triangle format. It can help solve problems involving collisions, forces, and changes in momentum.
What is the impact of the loss of kinetic energy in inelastic collisions on the overall momentum of the system?
In inelastic collisions, some kinetic energy is lost as heat or sound, which decreases the overall momentum of the system.
