torque

Front

-a property of force that makes an object rotate - NOT A FORCE

Back

kinetic friction

Front

occurs when there is relative motion (when there's sliding)

Back

newton

Front

kg m/s^2 unit of force

Back

static friction

Front

occurs when there is relative motion between the object

Back

gravitational force

Front

r is the distance between the two objects

Back

potential energy

Front

the energy an object or system has by virtue of its position Ug- gravitational potential energy △Ug= -W by gravity △Ug= mgh

Back

average velocity

Front

displacement/ time △x/△t

Back

centripetal acceleration

Front

centripetal= towards the center

Back

mu

Front

coefficient of friction

Back

conservation of momentum

Front

-the total linear momentum of an isolated system remains constant total p initial = p final

Back

inertia

Front

the property of objects to naturally resist changes in their states of motion

Back

momentum

Front

vector quantity given by p= mv

Back

tow dimensional vectors

Front

vectors that lie flat on a plane and can be written as the sum of a horizontal and vertical vector

Back

scalar

Front

a quantity that does not involve direction twp

Back

transitional equilibrium

Front

-sum of all forces acting on an object is 0 F net=0

Back

gravity

Front

-10 m/s^2

Back

Newton's first law

Front

an object at rest will stay at rest and an object in motion will stay in constant velocity unless a net force acts on it (law of inertia)

Back

Newton's third law

Front

for every action there is an equal but opposite reaction (action/ reaction pair)

Back

law of conservation of total energy

Front

Ki + Ui = Kf +Uf (initial mechanical energy Ei = final mechanical energy Ef)

Back

average speed formula

Front

total distance/ time d/t

Back

work

Front

-scalar -if a force F acts over a distance d and F is parallel to d, then the work done by F is the product of force and distance W=Fd

Back

Newton's second law

Front

Back

friction force

Front

the component of the contact force that's parallel to the surface

Back

kinetic energy

Front

the energy of an object due to motion K= (1/2)bh

Back

work energy theorem

Front

Back

center of mass

Front

Back

universal gravitational constant (G)=

Front

Back

newton's law of gravitation

Front

any two objects in the universe exert an attractive force on each other called the gravitational force

Back

slope of velocity-versus-time graph

Front

acceleration

Back

vector

Front

quantity that involves both magnitude and direction

Back

velocity

Front

speed plus direction

Back

total mechanical energy

Front

the sum of an object's kinetic and potential energies, denoted by E E= K+U

Back

weight (of an object)

Front

the gravitational force exerted on it by the Earth or whatever planet Fw or Fg= mg

Back

position

Front

location in some point in space

Back

elastic potential energy

Front

Us= (1/2) kx^2

Back

area between the graph and the t axis on a velocity-versus-time graph

Front

object's displacement

Back

centripetal force

Front

Back

impulse

Front

-pushing on an object for a certain amount of time -impulses cause a change in momentum -vector J= F△t or J=△p

Back

uniform circular motion

Front

-speed is constant velocity is not because the direction of velocity is always changing -in order to product acceleration there must be a force

Back

kinematics

Front

mathematical tools for describing motion in terms of displacement, velocity, and acceleration

Back

power

Front

the rate at which one does work given by P= W/t or P=Fv

Back

rotational equilibrium

Front

T net = 0

Back

F static friction, max=

Front

mus (FN) coefficient of friction x normal force

Back

work at an angle

Front

-a fore applied perpendicular to the intended direction of motion always does ZERO work

Back

displacement

Front

change in position

Back

acceleration

Front

change in velocity/ time △v/△t

Back

free-body (or force) diagram

Front

Back

normal force

Front

component of force that's perpendicular to the surface

slope of position-versus-time graph

Front

velocity

Back

F kinetic friction=

Front

muk x FN

Back

rotational inertia

Front

also known s the moment of inertia -the tendency of an object in motion to rotate until acted upon by an outside force

Back

static equilibrium

Front

an object is at rest
