force from the engine, accelerating the mass, opposed by drag of air and water resistance
that is called the net force; it is a vector sum of all the forces acting on it
All objects on earth have the force of Gravity acting on them.
Accoridng to Aristotle, the trolley would stop. According to Galileo the trolley would slow down and eventually stop.
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
Yes, the net force would be zero if all the forces acting on the object negated each other.
it just does. okay?
That would be the net force acting on the object.

If there are any forces acting on a stationary object, then they must be balanced, or it would no longer remain stationary.It is also possible that the object is already moving. In the forces are balanced on a moving object, the object would continue moving at the same speed and direction (velocity) that it already had.
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.
yes, since the forces are acting on just one body, the mass (m) in the equation F=ma is not changing, which would mean that the two accelerations (a) would have to be different. If the two accelerations are different then there is total acceleration in one direction (the resultant acceleration).
