Science 8 - Contact Forces Vocab Flashcards
Elastic Limit
The maximum amount a solid can deform without breaking.
Breaking Point
The moment when an object breaks.
Independent variable
What we purposefully change in an experiment.
Dependent variable
What we measure after changing the independent variable.
Constant/Controlled variable
Everything that we keep the same in the experiment.
In a ____ between two objects, the objects make contact with each other; sometimes something is ____, but not always.
collision; damaged
Different ____ or variables may cause objects to be damaged or not from a collision.
factors
Define Force

motion; shape
____ transfer occurs during a collision.
Energy
There is a ____(s) between objects when they make ____ during a collision.
force; contact
All solid objects ____ or ____ shape when Forces are applied on them during a collision.
deform; change
As ____ increases, so does the amount of deformation.
force

less
How much a solid object deforms is dependent upon the amount of ____ applied, the type of ____ it is made of, and its ____.
force; material; thickness
The strengths of contact forces between two objects are ____ but in the ____ directions.
the same; opposite
In a collision, both objects apply ___ strong forces on each other in ____ directions.

A ____ diagram can help represent the forces on the objects in a collision by considering each object separately.
free body
Increasing the ____ or ____ of a moving object increases its kinetic energy.
speed; mass
Forces have ____ and ____.
STRENGTH; DIRECTION
The more ____ that objects in a system have, the higher the ____ they can produce in a collision.
kinetic energy; peak force
Define Peak Force
The maximum force exerted on an object during a collision.
Increasing ____ and keeping the speed the same increased the kinetic energy of the object.
mass
