Key Concepts in Chapter 4 – Turning Effect of Forces
1. Moment of Force (Torque)
The chapter teaches how torque is calculated and how it depends on the magnitude of the force. It also explains the perpendicular distance from the pivot.
2. Equilibrium
In this chapter students grasp knowledge about the conditions of equilibrium and where all forces are balanced. They also learn about whether the object is stationary or moving at a constant speed.
3. Couple
This chapter teaches about the concept of a couple. They learn where two equal and opposite forces act on an object causing it to rotate without any movement.
4. Levers and Their Types
In this chapter, students learn about three types of levers: first-class, second-class, and third-class, along with examples like scissors, wheelbarrows, and fishing rods.
5. Center of Mass and Stability
Physics Chapter 4 also explains the center of mass and how it affects an object’s stability is crucial for solving real-world physics problems. This chapter explains a detailed clarification of how the center of mass is related to balance and stability.
