A large truck and a small car are moving at the same speed,traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?
The kinetic energy of an object is given by the equation KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
Although both the large truck and the small car are moving at the same speed, their masses are different. As the kinetic energy depends on mass, the object with greater mass will have a greater kinetic energy, assuming the velocity is the same.
Thus, the large truck, having a larger mass compared to the small car, will have more kinetic energy.
