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.

If two different masses have the same kinetic energy their momenta is?
The momenta would not be the same. Momentum is determined by both mass and velocity, so two objects with different masses and the same kinetic energy would have different momenta.
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.
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?
According to the kinetic theory of gases, the average kinetic energy of gas molecules in a room is proportional to temperature, not mass. However, the speed of individual gas molecules is inversely proportional to their mass - lighter molecules will move faster on average compared to heavier molecules at the same temperature. This is because kinetic energy is distributed among all molecules, and lighter molecules can move faster with the same amount of kinetic energy.
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 objects have the same temperature but different amounts of mass?
Yes, two objects can have the same temperature but different amounts of mass. Temperature is a measure of the average kinetic energy of particles in an object, while mass is the amount of matter in an object. So, it is possible for objects with different masses to have the same kinetic energy and therefore the same temperature.

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.

What is one form of energy that you use daily?
Electricity is a form of energy that most people use daily, whether it's for lighting, heating, cooking, or powering electronic devices.

Wind energy is an example of the energy of?
Wind energy is an example of the energy of motion (kinetic energy) from moving air masses. This energy is harnessed by wind turbines to generate electricity.
A friend says that in a mixture of gas in thermal equilibrium that the molecules have the same average kinetic energy Do you agree or disagree?
I agree. In a mixture of gases in thermal equilibrium, the molecules will have the same average kinetic energy regardless of their individual masses or properties. This is a result of the particles colliding and transferring energy, leading to a uniform distribution of kinetic energy among the gas molecules.
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, equal masses of different kinds of matter do not necessarily have the same thermal energy because thermal energy depends on factors such as the specific heat capacity and temperature of the substance. Different materials have different abilities to store and release thermal energy, so even if they have the same mass, their thermal energy content may vary.
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.
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.)
