vocab
describes the location of an object
position
distance/time
speed or average speed
the combination of all forces acting on an object
net force
1st law of motion
an object at rest remains at rest and an object in motion maintains its velocity unless it experiences an unbalanced force
a quantity with both size and direction
vector
a location to which you compare other locations
reference point
v2-v1/time
acceleration
contact forces
applied
spring
friction
air
second law
the acceleration of an object depends on the mass and amount of force applied
speed in a specific direction
velocity
a change in position over time
motion
mass x acceleration
force
non-contact forces
magnetic
electrical
gravitational
is the tendency of all objects to resist any change in motion
inertia or the second law
the rate at which velocity changes
acceleration
speed
mass x acceleration due to gravity
force of gravity
what determines the force of gravity
distance and mass
3rd law
when one object exerts force on a second object, the second object has an equal and opposite reaction
push or pull
force
acceleration in circular motion
centripetal acceleration
force x distance
work
