Will was riding his bike when a dog ran out in front of him. he slammed on his brakes. during this quick stop, some of the mechanical energy (his motion) was changed into

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.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
