Ma'am Nika told Grade 8, "Energy is everywhere at school." "KE is energy of motion: KE=1/2mv^2; PE is from height: PE=mgh." "Mechanical energy adds both: ME=KE+PE."

At the court, Migo passed to Ruru. "Dribbling is KE," said Ma'am Nika. Ruru jumped to shoot. "Higher means more PE," Ma'am Nika added. The ball falls, speeding; "KE rises, ME=KE+PE," Migo cheered.

After class, Migo rushed down the hallway. "Walk, please; KE rises with speed," Ma'am Nika warned. Migo slowed to a brisk walk. "Double speed, about four times KE, v^2," Ruru said.

In science class, Ruru and Migo pushed a book cart. "That motion is KE," Ma'am Nika said. They lifted a box; "higher gives PE," she added. "ME totals both: ME=KE+PE," the class echoed.
