Fields and Forces
Is gravity a pull or a push
Gravity is always a pull, never a push.
What is a controlled variable?
A control variable is any factor that is kept constant or held the same throughout a research study or experiment to ensure a fair test
What two main factors affect gravitational force? How?
The two main factors that affect gravitational force are mass and distance
What is a gravitational force?
Gravitational force is an invisible pulling force that exists between any two objects that have mass.
What is the difference between mass and weight?
Mass is the amount of matter something has. Weight measures the gravitational pull on an object’s mass.
What are manipulated/independent variables?
Manipulated/independent variables are the specific things that a researcher changes or controls on purpose in an experiment to test what happens. That is also on the X axis
What is a gravitational force field?
A gravitational force field is an invisible zone around any object with mass where other objects feel a pull toward it
What is a non-contact Force?
To attract or repel even from a distance
What are responding/Dendent variables?
A responding/dependent variable is the factor that you measure or record in an experiment to see how it changes that is on the Y axis
How does gravitational force affect objects in space
Gravitational force acts as an invisible glue in space, pulling objects toward each other based on their mass and distance.
What object exerts gravitational force on other objects
Every object with mass exerts a gravitational force on every other object with mass
How are weight and mass related to gravitational forces
Mass, weight, and gravity are directly related because weight is the measure of the gravitational force pulling on an object's mass.
How does gravitational force affect objects here on Earth? What causes ocean tides
Gravitational force keeps objects and people firmly on the ground, holds our atmosphere in place, and drives the regular rise and fall of ocean tides
How can gravitational force and force fields be studied if we can't see or touch them?
Scientists study invisible and untouchable gravitational forces and fields by observing how they change the motion and behavior of things we can see and measure.
