May the FORCE be with you
The force that pulls all objects toward Earth.
GRAVITY
A change in position.
MOTION
A statement that describes what you see happen.
OBSERVATION
Data that uses words instead of numbers.
QUALITATIVE
A push or a pull that can change motion.
FORCE
Two things a force can change about how something moves.
SPEED AND DIRECTION
A statement that describes what you see happen.
EXPLANATION
Data that uses numbers or measurements.
QUANTITATIVE
The force that slows objects moving through the air.
AIR RESISTANCE
What must be applied to make an object start moving, stop moving, or change direction.
FORCE
O vs E: “The object fell slowly.”
OBSERVATION
Q vs Q: "Taylor kicked the ball as hard as she could"
QUALITATIVE DATA
An object at rest will stay at rest unless acted on by an unbalanced force. An object in motion will stay in motion at the same speed and in the same direction unless acted on by an unbalanced force.
NEWTON'S FIRST LAW OF MOTION
The force that slows or stops motion when two surfaces touch.
FRICTION
What happens when air resistance increases on a falling object.
IT FALLS MORE SLOWLY
O vs E: “Air resistance slowed the object down.”
EXPLANATION
Q vs Q: "The basketball bounced lower due to 25% decrease in air"
For every action, there is an equal but opposite reaction.
NEWTON'S THIRD LAW OF MOTION
The scientist who described how forces affect motion using three laws.
ISAAC NEWTON
Why two objects can move differently even when the same force is acting on both.
VARIOUS FACTORS (SIZE, SHAPE, WEIGHT, ETC.)
We use both because observations show what happened and explanations tell why it happened
SCIENTISTS
Data that allows scientists to compare results precisely across experiments.
QUANTITATIVE DATA
The acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force.
