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

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,ifits rate
of change of velocity with time in
a
specified direction is constant

DECCELERATION: A decreasing velocity
or slowing down is usually called
retardation.::::::

QUESTION 2
Readings: S/n: 1,2,3,4,5,6,7
D: 100,90,80,70,60,50,40
D^2:
10000,8100,6400,4900,3600,2500,16
X1:
80.60,70.20,59.10,47.80,29.00,20.35, X2:
18.30,19.00,20.00,22.00,7.60,4.50,1.0
L
(X1-X2):
62.20,51.20,39.10,24.70,21.40,15.85,
PRECAUTIONS: -i ensured parallax when reading
the
metre rule.
-i ensured that the intensity or
source of light was maintained.
Expected Question: An illuminated object is placed on
the
axis of a converging lens and a
magnified image is obtained on
the
screen. If the distance of the image
from the lens is 45cm and the
magnification is 2,cal the focal
length
of lens.

SOLUTION:
V=45.00cm
m=2
u=?
M=v/u=45/2
22.5cm F=uv/v+u
22.5*45.00/22.5+45.00
=1012.5/67.5
=15cm

:::::::.QUESTION 3 Readings:
S/n: 1,2,3,4,5
L1: 20,40,60,80,100
L2: 10,15,25,35,45
I1(A): 0.50,0.40,0.32,0.22,0.14
I2(A): 0.58,0.53,0.45,0.41,0.37 I1^-1: 0.20,2.50,3.13,4.55,7.143
I2^1: 1.724,1.890,2.22,2.44,2.70 PRECAUTIONS:
-I will ensure that the key is
opened
when no reading is taken to avoid
battery wastage.
-I ensured tight connection -I ensured error due to parallax
when
taking
reading from the ameter
-i will ensure that the circuit
element are tightly connected to ensure
accurate result NEED TO KNOW:
-Electromotive force is the
potential
difference between the terminals
of
a cell when no current is flowing in
the circuit.
======= NOTE THAT ^ MEANS RAISE TO
POWER.
Eg: 2^4 Means 2 raise to power 4.
L^-2 means L raise to power
-2(minus two)
-COMMA MEANS NEXT LINE. Eg: x: 4,2,3,4,5 means that you
draw a table, then under x, you
will get 4, under 4 is 2, under 2 is
3, under 3 is 4 and so on……….
