Forces Flashcards
strength or energy as an attribute of physical action or movement.
force
an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Newtons 1st law
a tendency to do nothing or to remain unchanged.
Intertia
how much stuff something has
Mass
how heavy something is
Weight
W=mg
Formula for wheight
F=ma
Formula for force
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force
newtons 2nd law
It states that P before = P after.
newtons 3rd law
he quantity of motion of a moving body, measured as a product of its mass and velocity.
momentum
it is the resistance between 2 objects
friction
is the friction that exists between a stationary object and the surface on which it’s resting
static friction
the amount of retarding force between two objects that are moving relative to each other.
Kinetic friction
9.8 m/s2
gravitational constant
