The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
potential |
|
inherent |
|
gravitational |
|
kinetic |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
In the Periodic Table of the Elements, elements in the same column belong to the same:
atomic number |
|
family |
|
group |
|
period |
The columns of the Periodic Table are called groups and all elements in a group have the same number of electrons in their outer electron shell. The group that an element occupies generally determines its chemical properties as the number of outer shell electrons establishes the way it reacts with other elements to form molecules. So, because each element has the same number of electrons in its outer shell, each has similar reactivity.

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
Which of the following describes the Earth's outer core?
solid |
|
liquid |
|
primarily solid |
|
makes up most of the Earth's volume |
The Earth's core is divided into the liquid outer core (1,430 miles or 2,300 km radius) and the solid inner core (745 miles or 1,200 km radius).
