What Is Covered in ICSE Selina Class 10 Physics Chapter 1 Force?
Chapter 1 of Selina Class 10 Physics deals with the concept of Force in a very structured and progressive manner. The chapter begins by revisiting what force actually is — a push or pull that changes or tends to change the state of rest or motion of a body. It then moves into more advanced ideas like the turning effect of force, also called the moment of a force or torque.
Students learn that the moment of a force depends on two things: the magnitude of the force applied and the perpendicular distance from the pivot or fulcrum. This is a critical concept because it forms the base for problems involving levers, beams, and balanced systems.
The chapter further explains the principle of moments, which states that for a body in equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments. Students are also introduced to the concept of a couple — two equal and opposite forces acting on a body at different points, producing a turning effect without any translational motion. The resultant of a couple is always zero in terms of force, but the torque it produces is not zero.cThe centre of gravity is another important topic. Students learn how to find the centre of gravity of regular and irregular shapes and understand why it matters in everyday life. A lower centre of gravity generally means greater stability, which explains why racing cars are built low to the ground.

How to Solve Numericals in Chapter 1 Force Effectively?
Numericals in Chapter 1 are based primarily on the moment of force and the principle of moments. The key to solving these problems correctly lies in identifying the pivot point clearly, marking all forces and their distances from the pivot, and then applying the equilibrium condition. For instance, in problems where a uniform rod is balanced at a certain point with weights hanging from different ends, students must calculate the clockwise and anticlockwise moments separately. If the rod is uniform, its weight acts at its midpoint and must also be included in the calculation.
For couple-related problems, remember that the moment of a couple equals force multiplied by the perpendicular distance between the two forces. Students often make the error of calculating from only one force — the correct approach includes both. At Myclass24, all numerical solutions follow the ICSE-approved method of presentation, which makes them easy to adapt for board answer sheets directly.
Why Are These Solutions Important for ICSE Board Exams?
ICSE board exams are known for their depth and application-based questions. Chapter 1 on Force regularly appears in both short answer and long answer sections. Questions on the turning effect of force, principle of moments, and centre of gravity are almost always part of the question paper.
Using Myclass24's ICSE Selina Class 10 Physics Solutions helps students develop the habit of writing systematic answers, which directly improves their marks. The solutions are framed keeping the board's marking scheme in mind, so students know exactly where and how to include each step.
