Internal Forces
What is tension?
A force exerted by pulling on a string or rope that is connected to an object.
What is an applied force?
A force exerted on an object by a person or another object.
What is an action force?
A force exerted on an object in a particular direction.
Name a resource used before processing.
Wood, Wind, Solar, etc.
What is plasticity?
A property that leads to permanent changes in an object’s shape.
What is compression?
A force that squeezes, squashes, or compacts an object.
What is friction?
A force that opposes the movement of objects in contact with each other.
What is a reaction force?
A force that acts in the opposite direction of an action force.
Name a resource used after processing.
Oil, Nuclear
What is elasticity?
A property that enables temporary changes in an object’s shape.
What is shear?
A force that pushes parts of an object in opposite directions, resulting in bending or breaking.
What is elastic Force?
A force exerted on an object that is in contact with a compressed or stretched elastic object or spring.
What is Newton's Third Law?
For every action force, there is an equal and opposite reaction force.
What is an example of energy resource management?
Minimizing disruption to nature during resource extraction.
How do plasticity and elasticity differ?
Plasticity results in permanent change, while elasticity results in temporary change.
What is Torsion?
A force that twists an object.
How does friction work?
It opposes the movement of objects, causing them to slow down or stop.
Give an example of an action-reaction force.
When a bird flaps its wings down (action), it pushes the air down and moves up (reaction)
Discuss an advantage of renewable energy.
It reduces environmental impact and is sustainable.
Give an example of each property.
Bending a paper clip (plasticity) and stretching a rubber band (elasticity).
How do internal forces affect objects?
They can change the shape, size, or position of an object.
How do external forces change objects?
They can lead to internal forces that change the shape, size, or position of the objects.
How do forces affect motion?
Forces can change the speed or direction of an object's movement.
What is the impact of energy resource selection?
Accessibility, availability, societal, environmental, economic impacts.
How do material properties influence force interactions?
Different properties determine how materials respond to internal and external forces.
