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. 77 10 m/s 10,000 kg 10 m/s 5,000 kg The kinetic energy of a 10,000-kg vehicle is twice as much as the kinetic energy of a 5,000-kg vehicle when both are travelling at the same speed. Why is this so? The 10,000-kg vehicle has twice as much the mass of the 5,000-kg car. Since they are travelling at the same speed, using the formula of kinetic energy, KE = 1/2mv2 = 1/2(2m)v² Therefore, KE = 2(1/2mv2). The kinetic energy is doubl​
