An object with a mass of 375g is moving with a constant velocity. It has a force of -20 N applied to it. Determine the acceleration of the object. What is happening to the object?

The acceleration of object is - 0.53 and it is moving in opposite direction.

Explanation:

Given

mass of object, m = 375 kg

Force applied, F = -20 N = -20 Kg

acceleration of object, a = ?

We know that F = ma, where f is force, m is mass and a is acceleration.

therefore, a = F/m

                    = -20 Kg / 375 Kg

                    = - 0.53

When acceleration is negative, it means either the value  is decreasing or the object is moving in opposite direction.

In given case force is negative and so the negative value of acceleration means the object is moving in opposite direction.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
