Answer is: heat energy.
Braking is the process of controlling the velocity of an object (in this example bicycle) by inhibiting its motion.
Mechanical energy can be either kinetic or potential energy and has to do with the energy of position and motion of an object.
Kinetic energy is energy of the speed of an object and how much mass it has; basically how the object is moving.
Potential energy is type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band.
A mechanical brake applies a friction force to convert the kinetic energy of the bicycle into heat energy which then dissipates into the atmosphere.
Answer:
Explanation:
They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.
