This part of the Form 1 physics lesson focuses on correcting a previous assignment and introduces the concept of density calculation for spherical and rectangular objects, physics teacher Koki Christopher Titewondze said, it is an application of the formula density = mass/volume. The importance of stating the formula before working and knowing the difference between mass and volume is emphasized, encouraging the students to use 22/7 as the constant for PI when calculating the volume of a sphere.
