*Understanding the Fundamentals: Physics Paper 1*
Physics Paper 1 is the foundation of understanding the natural world around us. It introduces students to the principles governing motion, forces, energy, and matter. This paper lays the groundwork for advanced physics concepts and real-world a...
A LEVEL HeLP PHYSICS SEMINAR TO BE HELD ON SATURDAY
13TH NOVEMBER 2021 AT 10:00AM
INSTRUCTIONS TO STUDENTS AND TEACHERS:
Dear students and teachers we would like to welcome you to participate in the forthcoming
Physics seminar for senior five at 10:00a.m as they revise their physics concepts. The seminar
is organized by teachers under the Holistic eLearning programme .This is a free seminar and no
one should charge you any fees. The process to be followed by both the teachers and students
is suggested below:
1. Teachers share the Seminar questions with their students and ask for volunteers to discuss
any of the questions.
2. Teachers talk to the parents to allow the children participate as presenters in the seminar
on Saturday 13th November 2021 from 10:00am-1:00pm. Other students will just
be participants.
3. If your student is going to present then as the teacher(s) prepare her/him by looking
through the calculations made by the student. Then encourage the student to write out
the solution neatly in black pen including any graph. Then they scan or take a picture
and send to the teacher. They can also type out the solution in a word or PowerPoint
document and share with the teacher. .
4. The teacher could now train the student on how to present in zoom as far as sharing a
screen and using the whiteboard. Alternatively the students’ presentation will be loaded
on the computer screen and they explain to us their solution.
5. The teacher or student will hand in the solutions to Ronald Ddungu (0701433878(W)) or
Kaziba Stephen (0787698238(W)) by Thursday 11th November 2021and attend the
presenters practice session at 1:00p.m using the same seminar link below.The process here
is very important
Holistic eLearning Platform is inviting you to a scheduled A level Physics seminar.

PAPER ONE (Mechanics,Heat and Modern Physics)
1. (a) (i) State the principle of conservation of energy
(ii) Use the equations of motion to show that when an object is projected vertically
downwards from rest the mechanical energy is conserved
(b) (i) State newton’s laws of motion.
(ii) A ball of mass 500g is allowed to drop from rest from a point a distance 5m a
bove a horizontal concrete surface.When the ball first hits the floor,it rebounds
to a height of 3.0m .What is the speed of the ball just after the first collision
with the floor
(iii) If the collision lasts for 0.6minutes,find the average force which the floor exerts
on the ball
(c) (i) Differentiate between impulse and impact
(ii) Explain why when catching a fast moving ball the hands are drawn back while
the ball is being brought to rest
2. (a) (i) Define the terms moment of force and a couple
(ii) State the conditions for equilibrium of a rigid body under the action of coplanar
forces
