- How is momentum conserved if you lose kinetic energy?
The energy component of KE is the velocity Momentum is mass x velocity so, in a collision containing in-elasticity, if KE is lost to heat then that heat energy must have been supplied by the velocity of the object And since velocity has been lost to supply the heat then the overall momentum
- Why Is Momentum Conserved but Not Kinetic Energy in an Inelastic Collision?
In an inelastic collision, which is a type of collision where the colliding objects stick together and move as one, we observe that momentum is conserved while kinetic energy is not This means that the total momentum of the system before and after the collision remains the same, but the total kinetic energy changes
- Exploring Perfectly Inelastic Collisions: Momentum Kinetic Energy . . .
So why is kinetic energy not conserved while momentum is conserved in a perfectly inelastic collision? Where does the kinetic energy go when the objects collide perfectly inelastically? Why does conservation of momentum happen? Is momentum a type of energy? Thank you for your help
- Why momentum is conserved when a gun fires? (conceptual question)
I understand that conservation of motion comes from the action and reaction pairs of newton's third law When it is triggered, two forces appear that cancel when analyzed as a system My question is how is it that momentum is conserved if before the shot there was no force in the system and
- Is energy really conserved? | Page 2 • Physics Forums
What is "steady state", "no motion", and "resulting torques"? Since you have posted a labeled diagram, why don't you use those symbols in your text? Can you write down the formulas for energy input, energy output and stored energy using the symbols you have defined? Where is the maths that you
- Why is KE not conserved when momentum is? • Physics Forums
In elastic collisions, both kinetic energy (KE) and momentum are conserved, with bodies exchanging velocities, while in inelastic collisions, only momentum is conserved, resulting in a loss of KE The discussion highlights confusion about how momentum can be conserved when KE is not, emphasizing that momentum and KE depend on velocity in different ways The conservation of momentum is a

- AZING!Where Does Kinetic Energy Disappear in Inelastic Collisions?
In inelastic collisions, kinetic energy is not conserved because some of it is transformed into other forms of energy, such as heat or deformation of the colliding objects For example, when a 2kg cart collides with a 1kg cart, the initial total kinetic energy is calculated to be 4 5J, but after the collision, the kinetic energy drops to 4 17J, indicating a loss of 0 33J This energy loss
