Positions and Coordinates
The major line that runs left and right on a coordinate plane.
What is the x-axis?
The total amount of length you've traveled regardless of where you end up.
What is distance?
Action-to-reaction: every action will experience equal but opposite pushback.
What is Newton's 3rd Law?
When two objects collide, this law states that momentum isn't lost in the collision.
What is conservation of momentum?
The energy of something in motion.
What is kinetic energy?
This value has both magnitude and direction.
What is a vector?
What is displacement?
The basis for inertia - objects don't like change, whether they're in motion or at rest.
What is Newton's 1st Law?
What is impulse?
What is gravitational potential energy?
This value has magnitude, but no direction.
What is a scalar?
Kind of like speed, but more about displacement than distance.
What is velocity?
Mathematically speaking, how you would define forces using Newton's 2nd Law.
What is mass times acceleration?
Are you moving or standing still? You need to define this when solving physics problems.
What is the frame of reference?
A real gem of a unit, it describes energy and is otherwise known as kg m2/s2
What is a joule?
These standards of the metric system include values such as kilograms and meters.
What are SI units?
Floor it! The rate at which velocity changes over time.
What is acceleration?
The force that arises from the contact of one object against another.
What is friction?
The equation that calculates momentum uses these two values.
What is p = m x v?
When two objects collide and stick together, it's called this kind of collision.
What is an inelastic collision?
The official units of this value are kg x m / s2, although they have a famous physicist to thank for their other name.
What is a Newton?
If you drop something from a great height, rather than throwing it, this value is 0 m/s.
What is vi (or v initial, or initial velocity)?
The force that exists along the length of a flexible item.
The change in momentum can also be expressed as this mathematical relationship.
What is the spring constant?
