Physics 1114 lab final
what are the units for the period of a pendulum from the equation above
s
the frictional force that holds an object in place is called ______ friction
static
if you plotted x vs t^2 for an object falling from rest (Assuming down to be positive) what should the graph look like
straight line positive slope y intercept is zero
describe the graph that you would obtain if you plotted acceleration vs the mass ratio a= (ma/(m1+m2+ma+mf) g
straight line through the origin
given the equation, the slope of the graph of acceleration vs the mass ratio is a=(ma/(m1+m2+ma+mf) g
the acceleration due to gravity
if you drop a feather and penny in air, which one would hit the ground first
the penny will hit first
if you drop a feather and penny in a vacuum (no resistance) which one would hit the ground first
they will hit at the same time
what is the purpose of the friction rider
to counter balance the kineticc friction in the system
considering our pull system with a mass falling at a constant acceleration, what should the general snap of its position vs time graph look like
a curve with an increasing slope
considering our pulley system with a mass falling at a constant acceleration, what should the general shape of its velocity vs time graph look like
a straight line
if the pendulum is moved from the earth where g is 9/8 m/s^2 to jupiter where it is 26.0 m/s^2 the period of the pendulum will
decrease
Given the kinematics equation for the motion of an object falling from rest, x=.5g*t2), what kind of relationship is predicted between x and t?
displacement, x, is proportional to the square of the time, t62 x=k*t^2 where k is constant displacement,x, and time, t, obey a power law
the coefficient of friction can be zero, meaning there is no friction between the two surfaces
false
the coefficient of static friction is always ______ the coefficient of kinetic friction
greater than
a specific pendulum has a period of T, if the length of the string, L is increased the period will
increase
if the force applied on a object is greater than the force of kinetic friction the object will travel with ________ velocity
increasing
the frictional force that slows an object down while in motion is called ________ friction
kinetic
if the angle of the pendulum, increased from 2 degrees to 4 degrees the period will
remain the same
if the mass of the pendulum, m, is decreased the period will
remain the same
according to kinematics (x=.5gt^2) the acceleration is dependent only upon
where the object is located
