a change in position in relation to a reference point
motion
average speed
total distance÷ total time
velocity
speed in a given direction
the tendency of an object to resist in its motion
INERTIA
the force of gravity on a person or object on the surface of a planet
weight
Gravity depends on :
MASS and DISTANCE
a force that opposes the motion of an object [slows things down]
friction
gravity
the attraction between 2 objects
Newton's first law of motion
an object in motion will remain in motion unless acted upon by an outside force........an object at rest will remain at rest unless acted upon by an outside force
newtons first law of motion is also known as ....
INERTIA
the rule the buoyant force on an object is equal to the weight of the fluid that is displaces
Archimede's Principle
buoyancy
the ability to float
fomula for weight
W=Mx{g}
mass
the amount of matter in an object
the rule that a stream of fast moving fluid exerts less pressure than the surrounding fluid
bernoulis princple
scientific method
process that scientists use to solve problems
an object that travels around another object in space is called
satellite
a puss or pull
force
any force that causes an object to move in a circle
centripetal force
the force that pulls an object toward earth
gravity
to determine the acceleration rate of an object you must calculate the change in speed during each unit of....
TIME
rate of change in velocity (change in speed an /or direction)
acceleration
when forces are unbalanced the object
moves
when the only force acting on a falling object is gravity , the object is said to be
