what forces cause objects to move?
push and pull
100
Gravity is a _____ that acts on _______.
Gravity is a FORCE that acts on EVERYTHING.
100
Why do we do trials?
to make sure the data found is not a fluke
100
The distance an object _____ depends on the _____ that is applied to it.
The distance an object MOVES depends on the FORCE that is applied to it.
100
if I use the same amount of force pushing pencil as I do on a car, which one will move further? Why?
The greater the mass of the object, the less effect the force will have on an object.
200
Who is applying the force? What kind of force?
The dog, pulling
200
Gravity is a force that ____ all objects with _____ down to the ground.
Gravity is a force that PULLS all objects with MASS down to the ground.
200
What is procedure?
What you plan to do to gather the data.
200
Friction is a ______ that opposes _______ through direct _______.
Friction is a FORCE that opposes MOTION through direct CONTACT.
200
force is measured in _______.
Newtons
300
What is the difference between a push and a pull? use empirical evidence to support your conclusion.
A pushing force moves an object away from you whereas a pulling force moves an object towards you.
- you could push and then pull on a pencil, it moves away when pushed and comes toward you when pulled.
300
Wherever you are on Earth, ______ will ____ falling objects downward toward the ______ of the Earth.
Wherever you are on Earth, GRAVITY will PULL falling objects downward toward the CENTER of Earth.
300
Name 4 parts of the experiment process and what they are.
Question, Variables, Hypothesis, Experiment, Analyze data, concluded.
300
Give examples of a small, medium, and large amount of force on different objects. What can you conclude from these?
you got this bud
300
if nothing is moving, we can assume the forces are ______.
Balanced
400
most sports require ____ and _____. Give examples!
Most sports require the force pushing.
push: golfing, soccer, etc.
pull: fishing, archery, etc.
400
give empirical evidence of gravity in action.
Ex. drop a pencil.
400
How do you formulate evidence correctly?
introduction, supporting evidence (1-3), conclusion.
400
Use empirical evidence to compare the friction caused by two surfaces.
idk figure it out. lol.
400
Why is our weight different on the moon than on the Earth?
because weight is the amount of force that is pulling an object down due to gravity.
500
give an example of something that can pull or push without touching.
magnet, gravity (pull)
500
Can gravity be overcome by certain objects? Give an example.
Yes, an example is a house of cards or a rollercoaster.
500
What is the difference between the control and the test variable?
the control is left unchanged
the test variable is what does the test
500
Think about what friction is, and it's place in your everyday life. What does friction affect? Why?
Everything, because everything has texture.
500
give 3 examples each of balanced forces and unbalanced forces
yay!
