100
Anything that you can change in an experiment that might affect the outcome.
What is a variable?
100
an investigation designed to find out how variables affect outcomes.
What is an experiment?
100
using wheels
How do you reduce friction?
100
a force that pulls all objects toward one another.
What is gravity?
100
the larger the object, the greater the pull.
What is gravity?
200
a mass hanging from a fixed point that is free to swing back and forth.
What is a pendulum?
200
a force that resists motion between two objects in contact
What is friction?
200
use oil, grease, or lubricant
How do you reduce friction?
200
the greatest amount of fluid a container can hold.
What is capacity?
300
objects at rest will stay at rest and objects in motion stay in motion unless a force acts on them to move or change their motion.
What is Newton's First Law of Motion?
300
an experiment in which one variable is changed and the outcome is compared to a standard.
What is a controlled experiment?
400
an objects acceleration depends on the mass of the object and the size of the force.
What is Newton's Second Law of Motion?
500
for every force there is an equal opposite force.
What is Newton's Third Law of Motion?
