The rate at which an object changes its velocity is known as this.
What is acceleration?
Known as the "powerhouse" of the cell, this organelle generates most of the cell's supply of adenosine triphosphate (ATP).
What are mitochondria?
The Earth's crust is broken into large, moving pieces known by this name.
What are tectonic plates?
This is a region of spacetime where gravity is so strong that nothing, not even light, can escape.
What is a black hole?
This type of chemical bond involves the sharing of electron pairs between atoms.
What is a covalent bond?

This is the formula that describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit.
What is Ohm's Law (V=IR)?
This biological process results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes.
