What happenes in an inelastic collision?
In inelastic collisions, there is a net loss of kinetic energy after the collision has occurred.
A collision in which the total momentum and kinetic energy remain constant?
Kinetic energy is only conserved if the collision is elastic. All other collisions will have some loss of kinetic energy even when momentum is conserved.
What is the energy that is transfered through collisions?
Kinetic energy
How does increasing the temperature affect collisions?
It increases the number of high-energy collisions
Which fact is most important in explaining how enzymes speed reactions?
High-energy collisions are less common than low-energy collisions.
What does power loss in electrical transmission mean?
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines
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.
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 kind of collision does not conserve kinetic energy?
Usually all types of collisions, except for elastic collisions, as kinetic energy is usually lost as from deformation, heat, sound, etc.
What is typically transferred during atomic and molecular collisions?
Energy.
What is the effect of a catalyst on the required energy to achieve effective collisions?
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
What is the difference in Internal conversion and external conversion?
The processes of internal and external conversion differ by the method of energy loss. Internal conversion exploits the degrees of freedom within the molecule, whereas external conversion dissipates energy by collisions with other molecules.
