tt Flashcards
force
a push or pull extended on an object in order to change the motion of the object
motion
a change in position over time
net force
a combination of all the forces acting on an object.
speed
distance traveled per rate of time.
velocity
the speed and direction of an object
acceleration
the rate at which velocity changes over time
newtons first law
an object at rest will remain at rest at rest and object in motion wll remain in motion unless acted upon by an outside force.
newtons second law
force= mass x accelaration
newtons 3rd law
for every action there is an equal but opposite reaction
inertia
the tendecy of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the bus
friction
a force that resists motion
mass
the amount of matter in an object
gravity
an ttractive force that exist between all objects that have mass.
