Fix the Prefix
1,000,000,000 m = 1 ___m
Giga (G)
This is the direction of acceleration for any projectile, regardless of its motion
What is down?
This force always acts perpendicular to a surface; it's just the standard way of doing things
What is Normal force?
This type of potential energy is stored in an object based on its height off the ground.
What is Gravitational potential energy?
This term for "change in momentum" can also be represented by the letter J. If you have a heartbeat, you should be able to get this!
What is Impulse?
100 ___g = 1000 mg
centi (c)
It's the variable that's also defined as rate of change of position, and knowing it "positions" you for success!
What is velocity?
When an object is in equilibrium, it means that this type of force is always 0. Don't get tangled up in the details!
What is Net force?
This type of potential energy is both what we get from food and what we convert that energy to
What is Chemical potential energy?
This unit of momentum doesn't have a nickname, so saying it is a hassle
What is kgm/s?
20 ___L = 0.02 L
Unless this value is constant, the kinematic equations will not be true. Always keep an eye out!
What is Acceleration or Net Force
This type of force is directly proportional to the Normal force and a surface-dependent coefficient.
What is friction?
A basketball stores this type of energy when it hits the ground, which is why it will bounce back up even though its GPE and KE are both zero.
What is Elastic Potential Energy (EPE)?
A cannon experiences recoil when it fires a cannonball thanks to this momentum-based law
What is the Law of Conservation of Momentum?
0.000001 m = 1000 ___m
nano (n)
If an object's average velocity is 0, this other vector quantity will always be 0. Hey, sorry to disappoint!
What is displacement?
The tuning pegs on a stringed instrument change the pitch by increasing or decreasing this force acting on the strings.
What is tension?
No energy transfer is 100% efficient, so it will always result in at least some of this type of energy being produced in the transfer
What is heat or thermal energy?
This is the term for a collision between two objects that don't stick together or deform in the collision. They're tough enough to bounce back!
What is an elastic collison?
90 cg = 0.0009 ___g
kilo (k)
What is a parabola?
This type of force is one of the four fundamental forces that scientists recently proved also creates measurable waves from black holes
What is gravity?
A perpetual motion machine might violate the 2nd Law of Thermodynamics, but it wouldn't violate this related law focused on energy transfer
What is the Law of Conservation of Energy?
This variable would complete the calculus formula,
"___ = dp/dt"
What is force (F)?
