A possible answer to a scientific question
The 4 parts of a system
What are input, process, output, and feedback?
Change in position relative to a reference point
What is Motion?
A fish swimming has this kind of friction
What is Fluid Friction?
The ability to do work
What is Energy?

It looks like a straight line on a graph
What is a linear graph?
If a car travels 80 kilometers in 2 hours what is it's speed?
What is 40 km/hr?
An objects acceleration depends on the force on the object and the object's mass
What is Newton's second law?
Two types of Potential energy
What are Elastic and Gravitational?
An observation using characteristics
What is a qualitative observation?
The density formula
The formula for acceleration
What is final speed - initial speed divided by time?
Two ways to increase an object's momentum
What is Increase mass and Increase velocity?
The transformation that happens when a light switch is turned on.
Electrical energy transforms into light energy
The difference between a scientific law and scientific theory
What is laws are given facts, scientists don't debate them where theories are tested and may be added to, changed or eliminated altogether.
What is 48m3?
The units for acceleration
m/s2
In the absence of outside forces, when two objects interact, the amount of momentum is the same before and after the interaction.
What is the conservation of momentum?
What is energy is neither created or destroyed in an energy transformation, it is just transformed from one type to another?
