PHYSICS PRACTICAL SOLUTION SET
PLS NOTE THAT THESE ARE NOT THE REAL PHYSICS PRACTICAL ANSWERS BUT IS JUST A GUIDE TO PHYSICS PRACTICAL.
IT WILL HELP YOU TO STUDY YOUR PHYSICS PRACTICAL.
THEY ARE ASSUMED OR LIKELY QUESTIONS AND ANSWERS.
S/n: 1,2,3,4,5,6 L(cm):
-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 asthe 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.::::::
Readings: S/n: 1,2,3,4,5,6,7
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.
I2(A): 0.58,0.53,0.45,0.41,0.37 I1^-1: 0.20,2.50,3.13,4.55,7.143
-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
NEED TO KNOW:
-Electromotive force is the
difference between the terminals
a cell when no current is flowing in
NOTE THAT ^ MEANS RAISE TO
Eg: 2^4 Means 2 raise to power 4.
L^-2 means L raise to power
-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..........
