Assume 1 serving of fried chicken is 320 calories. Consider that a food calorie is equal to about 4 kJ of energy, how much energy in a serving size of the fried chicken compares in other situations.  For example, how does this compare to the amount of energy that's necessary to lift a fully-loaded pickup truck up three meters above the ground? Let's say the truck has a mass of 2500 kg.  Create a Energy-Interaction Model, and determine how much energy is necessary to lift the truck.

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
