How does density effect kinetic energy?
The more dense an object is the more kinetic engery it has
What effect does a catalyst have?
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Effect of catalyst on the rate of reverse step?
A catalyst increases the reverse rate of the reaction
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
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 effect of a catalyst on the required energy to acheieve effective collisions?
A catalyst lowers the activation energy of a reaction.
How does density effect kinetic energy?
The more dense an object is the more kinetic engery it has
The factor that has the greatest effect on kinetic energy is?
velocity!!
What will be the effect on kinetic energy by dubbling the mass?
the defining equation for kinetic energy= 1/2 mv2therefore kinetic energy is directly proportional to mass or as kinetic energy increases, mass increases proportionally (and vice versa).therefore if mass is doubled, the kinetic energy is also doubled.
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
What effect does a catalyst have?
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Effect of catalyst on the rate of reverse step?
A catalyst increases the reverse rate of the reaction
What is the effect on kinetic energy of molecule when temperature is increased?
increases
What is the effect of your push on the ball?
It gives the ball kinetic energy.
Is rolling down a hill potential or kinetic energy?
Yes, because potential energy is energy stored but kinetic is energy in motion.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10.
