A freight train has a mass of 270, 700 kg and has an acceleration of 40 m/s2. How much force is acting on the train? Formula:

1.08 x 10⁷N

Explanation:

Given parameters:

Mass of freight train  = 270700kg

Acceleration = 40m/s²

Unknown:

Force acting on the train = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

So;

        Force  = 270700 x 40   = 1.08 x 10⁷N

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
