Newtons 1st Law of Motion
Is the speed of an object in a specific direction.
Velocity
is the amount of matter in an object
Mass
what do we call an object that isn't moving?
Object at rest
which system is a way to measure things using units like meters and liters
Metric system
is the study of matter and energy
To push or pull something
Force
is the rate at which an object's speed changes
Acceleration
What do we call an object that is moving?
Object in motion
which system is another way to measure things, mainly used in the United States
Imperial system
is an educated guess about what will happen
hypothesis
is how fast an object is moving, regardless of direction
Speed
is the product of an object's mass and its velocity.
? = Mass × Velocity
momentum
Which of Newtons Laws states, "object at rest stays at rest, and an object in motion stays in motion unless acted on by an unbalanced force"
Newtons 1st Law
How many meters are in 5 kilometers?
5,000
is looking closely at your data to understand it
analysis
is a force that opposes motion between two surfaces that are touching
friction
occurs when the forces acting on an object are not equal, causing the object to move
unbalanced force
Which of Newtons Laws states, "For every action, there is an equal and opposite reaction"
Newtons 3rd Law
A yard has how many feet?
3 feet
when something changes how it looks or its shape (liquid, solid, or gas)
physical reaction
is the tendency of an object to stay at rest or keep moving unless acted on by a force.
Inertia
are equal in size but opposite in direction, resulting in no change in the object's motion.
balanced force
Which of Newtons Law states "acceleration of an object depends on its mass and the net force acting on it (F = ma)"
Newtons 2nd Law
water freezes at what degree Celsius
0 degrees celsius
What you change in an experiment
independent variable
