9
|
is a change in velocity. (speeding up, slowing down, changing direction)
|
10
|
a push or pull on an object without touching it
|
11
|
produces a net force that is not zero; changes the object's motion.
|
12
|
the motion of an object when gravity is the only force acting on the object.
|
14
|
the friction experienced by objects falling through the air
|
15

|
18

|
19
|
produces a net force that is zero; does not change the object's motion.
