Koki Christopher Titewondze's physics lesson for form one starts with the correction of assignments. Problems involve calculations of density of a bowling ball (spherical object) and a brick. The formula for calculating density (mass/volume) is stated. Volume calculation for spheres (4/3 * pi * radius^3 ) and rectangular blocks (length * width * height) is done. The next lesson will cover measurement of temperature. The volume is calculated first and then the Density.
