The Unit 4 Essential Question is...
What is "How Do Physics Help Us to Design a Safe and Efficient Car?"
The change in distance over time
What is speed?
Energy that is in motion?
What is kinetic?
Fire is an example of this kind of energy.
What is thermal or radiant energy?
The study of matter, energy, space, and time, and how they relate to one another
What is Physics?
Speed is calculated by using this formula:
What is distance/time?
Energy that is stored.
What is potential?
The form of energy that is due to the downward pull of Earth's gravity.
What is gravitational energy?
When one variable increases, the other decreases (and vice versa).
What is an inverse relationship?
What are 2 properties that affect an object's speed?
What are mass, incline, height, and/or distance?
This energy increases as height increases.
What is potential?
The type of energy with charged electrons.
What is electrical energy?
A direct relationship is...
What is --When one variable increases/decreases, so does the other.
The speed of a girl who rides her bike 25 meters in 2 minutes.
What is 12.5 meters per minute?
This energy increases as speed increases
What is kinetic?
This energy is vibrations moving through matter.
What is sound energy?
The ability to move, or cause change in matter.
What is Energy?
