Scientific Investigations
New data/evidence further develops scientific
knowledge
How does scientific knowledge develop?
Stored energy that begins at a height
What is potential energy?
Mass increases this type of force
What is gravitational force?
Forces that are equal in size and move in opposite directions
What is balanced force?
Examines the similarities/differences between things or conditions
What is a Comparative Investigation?
Energy that is able to do work usually at a low point
What is kinetic energy?
This force allows objects to stay on a surface
What is normal force?
Forces that are unequal in size and move in opposite directions
What are unbalanced forces?
This explains how and why things happen
What is a theory?
Energy can not be created or destroyed
What is the law of conservation of energy?
Forces that do not have to touch
What are non-contact forces?
The operation to calculate forces that are going in the opposite direction
What is subtraction?
When you copy and experiment to identify errors
What is replication?
Energy that decreases when height decreases
What is kinetic energy?
A force that attracts or repels using a magnetic field
What is magnetic force?
The operation to calculate forces that are going in the same direction
What is addition?
Collect data to draw conclusions about a natural or man made system
What is an Observational Investigation?
Increasing height increases this type of energy
What is potential energy?
A force that resists while one surface moves across another
What is friction?
The type of line on a graph when an object is at rest
What is a horizontal line?
