Is mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
When to use law of momentum to find velocity rather than law of conservation of energy?
While energy is ALWAYS conserved, this isn't always useful for calculations, since MECHANICAL ENERGY - the energy that can be easily calculated - is NOT always conserved. On the other hand, momentum is always conserved, whether a collision is elastic or inelastic. (In an elastic collision, energy is also conserved.) Thus, conservation of momentum is often more useful for calculations involving collisions.
In situations is mechanical energy conserved?
It depends on the situation
The conservation of energy explains that energy?
The law of conservation of energy states that all energy in the universe is conserved. It can not be created nor destroyed, but it can be interchanged between mechanical and non-mechanical energy.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.

When you throw a matter from a height why mechanical energy is not conserved?
When you throw matter from a height, mechanical energy is not conserved by you, but it is by the matter. You are exerting mechanical energy to throw the object, and the matter is conserving it by not having to do any work to move.
In situations is mechanical energy conserved?
It depends on the situation
Can an objects mechanical energy change?
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.

When only mechanical energy acts on an object what is conserved?
gravity
Which energy is always conserved?
kinetic energy..........
