Two books with different masses fall off the same bookshelf as they fall which one has more kinetic energy?

Since kinetic energy is dependent on mass (KE = 0.5 * mv^2), the book with the larger mass will have more kinetic energy. This book would also have the larger gravitational potential energy.

How do two kinetic energies compare with one another?
You use the formula for kinetic energy for two different objects, inserting the corresponding speeds and masses, then you can compare them.
If two different masses have the same kinetic energy their momenta is?
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.
What is one form of energy that you use daily?
glucose and for a short energy burst kinetic energy, stored in muscle masses
What happens to kinetic energy when you decrease the mass?
Kinetic energy = K.E. = 1/2 (m)(v)2. Since mass, m, is part of this equation, we see that two particles of equal velocity but of different masses have different kinetic energies. In the case of equal velocities, the particle with the lesser mass will have the lower kinetic energy. Remember that momentum is the derivative of K.E., and so the momentum of an object is also related to the mass of an object as well.

Can two people be moving at the different speeds and have the same kinetic energy?
Sure. Kinetic energy depends on both mass and speed. So two objects could have different speeds, but if their masses are also different by just the right amount, their KE's could be equal.

How does heating an evaporating dish affect its mass?
as temperature rises the kinetic energy rises so as the masses youll weighed .
A bomb of 12kg explodes in two pieces of masses 4kg and 8kg The velocity of 8kg mass is 6msecThe kinetic energy of the other mass is?
Assuming both pieces are traveling at 6m/s, the 4kg mass has a kinetic energy of 72 joules.
If women fastpitch softball the picture shows the ball at 3 30 40 mins in the base of the masses 108 kilograms what is the kinetic energy of the softball?
The kinetic energy of the softball at 3.30 m s the and a mass of 1.08 kilograms is 3.564 joules.
Do equal masses of different kinds of matter have the same thermal energy?
NO
What type of energy is contained in a moving bullet?
velocity Kinetic energy is equal to (1/2)mv2, where m is mass and v is velocity. Higher velocities contribute even more to higher kinetic energies than higher masses since velocity is squared in the equation. For comparison, a 6.35 kg bowling ball moving at 7.6 m/s will have a kinetic energy of 183.4 Joules. A 0.02 kg bullet moving at 200 m/s will have a kinetic energy of 400 Joules. (Increase that to 300 m/s, and the kinetic energy moves up to 900 Joules.)
Do things with larger masses have larger velcities?
The question "Do things with larger masses have larger velocities?", by itself, is meaningless, as you did not provide enough information. Things with larger masses do require more force to accelerate them than things with smaller masses. Things with larger masses do have more kinetic energy than things with smaller masses for the same velocity.
