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?
If mixed together, molecules with various masses will move at different speeds related to their mass.
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.
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.
If two objects have the same velocity do they have the same momentum?
No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)

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
How do you calculate velocity after perfectly collision?
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.
