Yes becuase it is going up alot of hills and when it is coming down it is working
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
The more massive horse that is moving at the same speed will have greater kinetic energy. How do you define large and small? A small fat horse may have more mass than a large skinny horse.
no.
No. Larger velocity = larger Kinetic Energy.
Yes.
The average kinetic energy of the individual particles gets larger in this case.

Velocity of molecular movement is lower in larger molecules because it takes more energy to get the larger molecule moving. On the other hand, smaller molecules move more rapidly causing its velocity to be higher.
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.
Maybe and maybe not. It depends on the speed of the two objects. A small object moving very fast might have more kinetic energy than a large object moving slowly.
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.
Other things being equal, both potential and kinetic energy will be larger if the mass is greater.
