Force
What happens when an unbalanced force acts on an object?
The object accelerates (changes speed or direction)
What is mass?
Mass is the measurement of the amount of matter (or "stuff") inside an object.
What is acceleration?
What is motion?
Motion is a change in the position of an object over time relative to a reference point.
What is the name of the nation where the story takes place?
Panem
What is a force?
A push or a pull acting upon an object.
Does mass change based on location (like going to the Moon)?
No
Is acceleration a scalar or a vector quantity?
vector
What is velocity?
Velocity is the speed of an object in a specific direction.
What district does Katniss Everdeen come from?
District 12
What is the SI unit of force?
Newton (N).
What tool is used to measure mass?
A balance or balance scale.
What is acceleration?
Acceleration is the rate at which an object changes its velocity (speeding up, slowing down, or changing direction).
What is inertia?
Inertia is the tendency of an object to resist changes in its state of motion (an object at rest stays at rest, or in motion stays in motion).
Why does Katniss go into the Hunger Games?
She volunteers to take her sister Prim’s place.
What is friction?
A force that acts in the opposite direction of motion when two surfaces touch.
Is mass a scalar or vector quantity?
Scalar (it only has magnitude, not direction).
What does "negative acceleration" mean?
deceleration
What is friction?
Friction is a force that acts against motion between two surfaces that are touching, causing them to slow down.
Who is Haymitch Abernathy?
A former winner who mentors Katniss and Peeta
What is inertia?
The tendency of an object to resist changes in its motion.
What is the approximate mass of a large paperclip?
About 1 gram
What is the standard SI unit for acceleration?
The unit is meters per second squared, expressed as m/s2
What is gravity?
Gravity is a non-contact force that pulls objects with mass toward each other.
What are "Tracker Jackers"?
Genetically altered, venomous wasp
