Vocabulary
the type of force that causes an object to change its motion
unbalanced force
This states that an object in motion remains in motion unless an unbalanced force acts upon it.
What is Newton's First Law of Motion?
Newton created ________ (how many?) laws of motion.
What is 3 laws of motion.
This law describes the need for an unbalanced force in order for an object to undergo an acceleration (aka, a change in speed).
What is Newton's Second Law of Motion?
The line or course along which something moves.
direction
What is the force that pulls two objects toward one another, generally downward?
gravity
This term means a push or a pull.
What is force?
What century did Newton live in?
What is the 17th century.
This law states that the mass of an object is inversely proportional to the acceleration that is undergoes.
What is Newton's Second Law of Motion?
flow of thermal (heat) energy between things that are touching.
conduction
the distance from one object to another is changing
motion
This is the combination of all the forces acting on an object
Net force
This is a push or pull.
What is a Force.
True or False: If an object is pushed with more force, it will move faster, or have a greater acceleration.
True
the transfer of energy by electromagnetic waves. The sun is Earth’s main source of electromagnetic waves.
radiation
a change in a moving object's speed or direction
acceleration
What will happen to an object at rest when balanced forces act on it
It will remain at rest
This is a resistance to change.
What is Inertia
This is one form of the equation that represents Newton's Second Law of Motion.
What is F=ma, a=F/m, or m=F/a.
a usually reversible change in the physical properties of a substance, as size or shape: Freezing a liquid is a
physical change
What is inertia?
an object's tendency to resist any change in its motion
The forces acting on an object that combine and form a net force that is not zero
Unbalanced forces
This is a force of resistance between 2 objects,
What is Friction
Forces always come this way
What are pairs
The way we learn and study the world around us through a process of steps.
scientific method
