Is friction a force?
Yes
Define Mass
Amount of matter in an object
What is a force?
A push or pull.
What is Newton's third law?
The Law of Action and Reaction.
What is criteria?
Goals/things that could be nice to have.
What type of force is friction?
Define collision
An event in which two bodies(objects) exert two(or more) forces on each other.
What are balanced forces?
Forces that are equal in size and opposite in direction.
What is the meaning of the third law?
For every action there is an equal and opposite reaction.
What is a contraint?
Must haves in an investigation.
Who discovered gravity?
Isaac Newton.
Define Acceleration
The change in motion due to the object's changing speed.
What are unbalanced forces?
A force applied in one direction is greater than the force applied in the opposite direction.
What is Newton's first law?
The Law of Inertia.
What is a dependent variable?
Measured results of an investigation.
What causes gravity on Earth?
All of Earth's mass.
What is a Fair Investigation?
An investigation with carefully chosen variables.
What is a Constant Variable?
Variables that are kept the same.
What is the meaning of the first law?
An object at rest will stay at rest and an object in motion will stay in motion unless another force acts on it.
What is an independent variable?
What is changed or tested in an investigation.
Does the distance from an object affect how far it moves?
Yes
What's a Standard of Comparison?
Something used to judge or measure against
What are Force Pairs?
Equal and opposite forces always present when two objects are in contact.
What is Newton's second law?
Force = Mass + Acceleration
How does the mass of an object change how the object will move when a force is acted on it?
The more mass an object contains, the less movement the object has when it happens.
