according to newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off.
Umnica [9.8K]

Unless acted upon by an external force, an object in motion tends to stay in motion, and an object at rest prefers to stay at rest.

We can also see that we regress when a car abruptly begins to move from a condition of rest. The inertia of repose also contributes to this. Our bodies have a tendency to stay in a condition of rest, but as soon as the automobile starts moving, we start to regress.

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. Second Law of Motion by Newton.

two projectiles are fired at equal speeds but differentangles. one is fired at an angle of 30 degrees and the other at 60degrees
zheka24 [161]

Answer:

a) 30 degree

Explanation:

As we know that time of flight of the projectile depends on the the vertical component of the velocity always

It is given as

T = \frac{2v_y}{g}

now we know that

v_y = vsin\theta

so we will have

T = \frac{2vsin\theta}{g}

since we know that two projectiles are projected at same speed but different angles

so smaller the angle will take smaller time

so it would be 30 degree projectile which will take smaller time

2. ¿Puede haber trabajo en un sistema si no hay movimiento
Andru [333]

Answer:

d. No, porque la ecuación de trabajo lo define.

Explanation:

En Física, el trabajo realizado se puede definir como la cantidad de energía transferida cuando un objeto o cuerpo se mueve a lo largo de una distancia debido a la acción de una fuerza externa.

Matemáticamente, el trabajo realizado viene dado por la fórmula;

W = F * d

<u>Dónde;</u>

  • W es el trabajo realizado.
  • F representa la fuerza que actúa sobre un cuerpo.
  • d representa la distancia recorrida por el cuerpo.

Por lo tanto, podemos deducir de la definición de trabajo y su fórmula que el trabajo se realiza cuando un objeto (cuerpo) se mueve una distancia o experimenta cualquier forma de desplazamiento mientras transfiere energía.
