tendency of an object to resist change
fundamental force of nature
gravity, electricity, magnetism
if velocity is constant, what is acceleration?
what is kinematics
study of motion with regards to its force
is weight a scalar quantity or vector quantity?
which is usually larger, coefficient of static friction or coefficient of kinetic friction? why?
static, it has to overcome inertia
list newtons 3 laws of motion
1) law of inertia
3) equal and opposite reactions
what is Fn
what force is always opposite?
what is the SI unit of weight?
if an object has a mass of 12 kg on earth, what is its mass on the moon
12 kg, mass stays the same
what is the number for acceleration due to gravity?
mass is a measure of an objects _________
is weight a contact force?
no, it has gravity
what force is applied to a bungee cord?
if acceleration of an object is zero, does that mean there are no forces in it?
no, all forces are balanced
to determine the _______ of a vector, a coordinate system must be chosen.
the force of _____ depends on the normal force exerted by an object when there is no motion between two surfaces
the _______ is a force that puts an object into equilibrium
_______ is always less than the maximum value of static friction
breaking a vector down into its components is called _____
the _____ is greater than the coefficient of kinetic friction
coeffictient of static friction
T/F the representation of a vector has both LENGTH and direction
T/F velocity and speed are both quantities, but only SPEED is a vector
T/F MASS is not a vector
T/F FORCE is a vector because it has both length and direction
T/F when you represent a vector on a coordinate system, the tail of the vector is ALWAYS placed on the origin
T/F if two vectors are represented on a coordinate system, and they point in the same direction and have the same length, the vectors are EQUIVALENT
T/F when adding two vectors on a graph, you place them TAIL-to-tail

the vector sum of two or more forces acting on object is the _____
the net force of an object in ____ is zero
a force exerted by a fluid on an object moving through the fluid is a _____
the force exerted on on a scale by an object and other forces acting upon the object is the _____
a force that acts on an object by touching it is a _____
a perpendicular contact force exerted by a surface on another object is a _____
a defined object or group of objects is a _____
the identifiable cause of the force is the ______
