The Unit 4 Essential Question is...
What is "How Does Physics Help Us to Design a Safe and Efficient Car?"
The change in distance over time
What is speed?
The energy of motion.
What is kinetic?
Fire is an example of these kinds of energy.
What is thermal and 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 and due to an object's height or compression.
What is potential?
The type of energy with charged electrons.
What is electrical 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?
What are 3 energy transformations that happen when a car is turned on and driven down a road?
chemical (battery) > mechanical (driving) > thermal (burning gas) > sound (rumble of the car)
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?
What are 3 energy transformations that happen when a meal is cooked over a gas stove?
chemical (in the gas) > thermal and radiant (burning the gas to cook the food) > mechanical (food being cooked, releasing the stored energy) > sound
The ability to move or cause change in matter.
What is Energy?
A tree grows at a speed of 6 inches/month. How many years would it take the tree to grow 18 feet?
What is 3 years
Object A has a mass of 30 grams and object B has a mass of 50 grams. Which object has more gravitational potential energy?
What is object B?
Where is chemical energy stored?
What is in the bonds of atoms and molecules?
