QUESTION 1
Reading:
S/n: 1,2,3,4,5,6
L(cm): 150.0,120.0,100.0,80.0,60.0,40.0
t(sec):
4.800,4.100,3.300,2.600,1.900,1.200
t^-1(Sec^-1):
0.208,0.244,0.303,0.385,0.526,0.833
t^2(sec^2):
23.40,16.81,10.89,6.76,3.61,1.44
L/t^2(m/s^2):
6.510,7.139,9.183,11.83,16.6,27.7
Precautions:
-I ensured the experiment was not
affected by air interference when
determining the balance points
-I ensured the mass roll down freely
as being influenced under gravity
-I ensured that the readings were
taken without any error
DEFINITIONS YOU NEED TO KNOW:
FORCE OF GRAVITY: The total
gravitational force which acts on a
body and so enables it,in turn to
exert an equal force on its support
DISPLACEMENT: This Is defined as the
distance moved in a specified
direction
copie from nnaijahero.net
NEWTONIAN MECHANICS: This is defined as
the rate of change of distance moved
with time in a specified direction or
rate of change of displacement
UNIFORM VELOCITY: A body moved
with uniform velocity if its rate of
change of distance moved with time
in a specified direction is constant
ACCELERATION: This is defined as the rate
of change of velocity with time
INERTIA: The tendency of a body to
remain at rest or if moving,to
continue its motion in a straight line

UNIFORM ACCERATION: A body moved
with uniform acceleration,if its rate
of change of velocity with time in a
specified direction is constant
DECCELERATION: A decreasing velocity
or slowing down is usually called
retardation.
