All None

Newton's second law (words)
acceleration is proportional to net force and inversely proportional to mass
A gas or a liquid
air resistance
Fluid friction acting on an object moving through the air.
Free-body diagram
A diagram showing all the the forces acting on an object.
_______ is the measure of force exerted on a unit area of surface
a unit of pressure
Terminal Speed
The speed at which the acceleration of a falling object is zero because friction (air resistance) balances the weight.
Terminal Velocity
Greatest velocity an object can reach is called _______.
acceleration causes
change in velocity (is caused by)
net force causes
acceleration (is caused by)
Newton's second law (equation)
a body of coherent matter, usually of indefinite shape and often of considerable size
Newtons Second Law Of Motion
A greater unbalanced external force causes a greater acceleration of an object in the direction of the force.
greater unbalanced external force
is required to accelerate an object with more mass F=ma force equals mass x acceleration A=F/M
Gravity force
pulls stronger on an object with more force than an object with less mass
mass and weight
their is a direct relationship between these two are the same
a type of design that minimizes air resistance
force created due to air resistance
