Newtons Law
What does Newton’s First Law say about how objects move or stay still?
They stay at rest or keep moving unless an unbalanced force acts on them
Which internal force stretches or pulls material apart?
Tension
What type of energy includes coal, oil, and natural gas?
Non-renewable Energy
What is one energy source used before processing?
Wind, Water, or Wood
What types of energy help reduce greenhouse gas emissions?
Solar and Wind energy
What is it called when equal forces act on an object and it doesn’t move?
Equillibrium
Which internal force squeezes or pushes material together?
Compression
What type of energy includes solar and wind power?
Renewable Energy
Is using a water wheel to grind grain an example of energy before or after processing?
Before processing
What is it called when land is cleaned and restored after mining or drilling?
Restoration of extraction areas
If one person pushes a ball harder than another person, what happens?
The ball moves toward the stronger force
Which internal force twists an object?
Torsion
Why is natural gas considered non-renewable?
It takes millions of years to form, much slower than we consume it.
Is hydroelectricity produced before or after processing?
after processing
What environmental responsibility involves protecting animal habitats and plants?
Minimal disruption to nature
What is the combined force that determines an object’s motion when forces act in different directions?
The resultant force
What type of force includes wind, snow, earthquakes, and traffic?
External Forces
What machine does wind spin to make electricity?
A Turbine
When wood is burned in a fire for heat, is it used before or after processing?
Before processing
What practice helps prevent pollution by safely storing or treating harmful waste?
Waste management
What are the four internal forces that act inside structures?
Tension, compression, torsion, shear
What must engineers consider when designing structures such as bridges?
How internal and external forces act on the structure
What effect in solar panels causes electrons to move when hit by sunlight?
The Photovoltaic effect
How is wind used both before and after processing?
Before: powering windmills for grinding grain or sailing ships.
After: spinning turbines to generate electricity.
Why must companies work with Indigenous communities before using their land for energy projects?
To respect land and resource rights and protect culturally important areas.
