The collision between two helium atoms is perfectly elastic so that momentum is conserved?
Momentum is always conserved in any type of collision. Energy conservation, however, is dependant on elasticity. In a perfectly elastic collision all energy is conserved.
What is conserved sum of potential and kinetic energy?
The sum of potential and kinetic energy is called "mechanical energy". This is NOT conserved, though - unless you consider the microscopic scale, in which case (for example) heat energy is a type of kinetic energy. In this case, the sum is simply the total energy, and the total energy IS conserved.
Does momentum conserved during collisions?
Energy, if collision is rigid, total momentum is a constant also.
Why is it difficult to use the law of conservation of energy to calculate the effects of a collision?
Depending on the type of collission, a variable amount of energy is "lost" in the sense that it is converted from kinetic energy to heat, usually.
What type of energy is produce when biking?
Kinetic energy. Kinetic is movement

Distinguish beween and elastic and inelastic collision for wich type of collision is momentum conserved?
Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
Does momentum conserved during collisions?
Energy, if collision is rigid, total momentum is a constant also.
In what situations does the law of conservation of energy not apply?
In general Conservation of Energy does not hold internal to a system, it only holds at the boundary of the system. This is where the limits of the system are. Internal to the system energy is not conserved. The situations where the Conservation does not apply is where the force is not zero or the first derivative of energy is not zero.
Is thermal energy a type of kinetic energy?
yes it is a kinetic energy. yes it is a kinetic energy.

Is Motion energy a type of kinetic or potential energy?
kinetic
Which type of energy becomes greater as the kinetic energy becomes greater?
The kinetic type does.
What is collision?
A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time.Although the most common colloquial use of the word "collision" refers to accidents in which two or more objects collide, the scientific use of the word "collision" implies nothing about the magnitude of the forces.Types of collisionsA perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. In reality, any macroscopic collision between objects will convert some kinetic energy to internal energy and other forms of energy, so no large scale impacts are perfectly elastic. However, some problems are sufficiently close to perfectly elastic that they can be approximated as such. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Momentum is conserved in inelastic collisions (as it is for elastic collisions), but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.Collisions in ideal gases approach perfectly elastic collisions, as do scattering interactions of sub-atomic particles which are deflected by the electromagnetic force. Some large-scale interactions like the slingshot type gravitational interactions between satellites and planets are perfectly elastic.Collisions between hard spheres may be nearly elastic, so it is useful to calculate the limiting case of an elastic collision. The assumption of conservation of momentum as well as the conservation of kinetic energy makes possible the calculation of the final velocities in two-body collisions.
Is gravity kinetic energy?
There is no "gravity kinetic energy". There is gravitational energy (a type of potential energy), and - separately - there is kinetic energy (the energy of movement).
What type of energy is produce when biking?
Kinetic energy. Kinetic is movement
