Newton's 1st Law
define Newton's 1st law
object at rest will remain at rest
define Newton's 2nd law of motion
acceleration depends on mass and force
momentum is
movement of an object based on mass and velocity
Define Motion
distance from another object is changing
acceleration
change in speed or direction
inertia
an object's resistance to a change in motion
picking up a lemon
what are the action reaction forces in a pogo stick jump?
person jumping on the pogo stick; pogo stick pushing up on the person.
Reference Point
stationary object used to determine if something is moving
Measures force
Newton (N)
air resistance
type of fluid friction
Is mass related to inertia?
yes
do action-reaction pairs cancel each other out?
no they are acting on different objects
SI unit of length
international system of units which is meter
Unbalanced force
changes an object's motion
terminal velocity
maximum speed of an object falling when air resistance eqauls the weight of the object
how could you make a mass accelerate at a greater rate?
pull or push harder
action-reaction pairs
Equation to calculate speed
speed equals distance divided by time
Balanced force
equal forces acting on an object
free fall
formula to calculate acceleration
acceleration equals net force divided by mass
define Newton's 3rd law
equal and opposite forces exerted on each other
velocity
speed and direction
friction
