Answer:
Both speed and mass causes the kinetic energy to change.
Explanation:
The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)
The relation between the mass, speed of the object can be represented as

Kinetic energy$=\frac{1}{2} m \times v^{2}$
Thus when there is a increase in the mass and speed, the kinetic energy will also increase
Answer:
It depends on the bone and what you mean by function, if you mean live and be "normal" then probably.
Explanation:
A tooth is a bone, and there are plenty of people missing some. They can definitely function without one. If a person is missing on the bones that makes up the skull they might need to be more careful or get surgery in order to properly protect their brain.
