kilo grams

# data[].attributes.body
measure of the amount of matter in an object

# data[].attributes.body
weight changes when gravity changes

# data[].attributes.body
measure of the gravitational force exerted on an object

# data[].attributes.body
The size of the force depends on the masses of the objects and the distance between the objects

# data[].attributes.body
the more mass, the greater the pull of gravity

# data[].attributes.body
a force of attraction between objects

# data[].attributes.body
two thing moving in the same direction- you add their velocities

two things moving in different directions- you subtract their velocities

# data[].attributes.body
anything not moving;

tree

lamp post

fire hydrant

etc.

# data[].attributes.body
combining velocities

# data[].attributes.body
speed

direction

# data[].attributes.body
an object that appears to stay in the same place

# data[].attributes.body
the rate at which velocity changes overtime; an object accelerates if its speed, direction, or both change

# data[].attributes.body
the speed of an object in a particular direction

# data[].attributes.body
the distance traveled divided by the time during which the motion occured

# data[].attributes.body
an object's change in position related to a reference point

# data[].attributes.body
average speed = distance/ time
average velocity = speed with a direction
time = distance/ speed
average acceleration = (final velocity - starting velocity) / (time it takes to change velocity)

# data[].attributes.body
a force that opposes motion
