Why is it useful to model systems that use energy?

Chemistry
1 answer:
Airida [17]3 years ago
7 0

Answer:

Energy modelling can be described as a system to make simulations or computerized models of systems which use energy. This makes it easier to analyze and access such systems which use energy. By this approach, there are lesser chances for the energy to be wasted and fewer chances for any energy-related experiments to go wrong. As such kind of experiments can be dangerous hence it is essential that models be made first.

Los hermanos Ana Victoria y José Leonardo están patinando en el hielo, con 25 y 20 kg respectivamente de masa, si Victoria empuj
andreyandreev [35.5K]

Utiliando las leyes de Newton encontraremos que la aceleración de Ana es -1.6 m/s^2.

La segunda ley de Newton dice que:

F = m*a

Fuerza es igual a masa por aceleración.

La tercera ley de Newton dice que cuando dos objetos interactuan, cadan objeto ejerce una fuerza de <u>igual magnitud pero opuesta direccion</u> en el otro.

Ahora veamos como aplicar esto.

Sabemos que la niña empuja al niño, asumamos que con una fuerza F.

Tendremos entonces la ecuación:

F = 20kg*(2m/s^2) = 40N

Y por la tercer ley de Newton, esta misma fuerza (pero en opuesta dirección) se aplica a la niña, entonces tendremos:

-40N = 25kg*a

-40N/25kg = a = -1.6 m/s²

La aceleración con la que retrosede la niña es -1.6 m/s²
