Activity 2. Kinetic energy
Objective: After performing this activity you should be able to investigate that increasing or reducing the mass and/or speed affect/s the kinetic energy of the object the situations and explanations below are introduced to guide and help you answer the questions that follow.
Situation A: two vehicles of different mass moving at same speed.
(Ang hinahanap po dito is yung sasagutan sa table 1 which is yung "Kinetic Energy".)
Question:
1. which of the numbers above is KE largest?
2. which of the numbers above is KE smallest?
3. rank the KE of the numbers above from smallest to largest.
(wag naman po sana kayong manloko para lang sa points. Salamat po.)
