The forces are vectors, the vectors are added together, therefore forces acting against each other will cancel each other out, forces acting in the same direction will add up.
For forces acting in different directions you can use Pythagorean theorem to add them up.
The sum is what gives the body an acceleration, depending on it's mass. ( F=m*a )

∙ 9y agoThe resultant force of a number of balanced forces acting on a body is zero force.
The reason is because any force in one direction is always canceled out by another equal force but in the opposite direction. This is what is meant by balanced forces. For every force in the positive direction, there is also an equal negative force in the negative direction.
So the forces all add up to Zero. No net force at all.

If a crate is stationary on an incline does it mean that it is in the state of equilibrium?
If a crate placed on an inclined plane is moving at constant velocity or not moving at all -- which is really a special case of constant velocity where the velocity is zero -- then the sum of the forces acting upon it is zero. We can say that it is in a state of equilibrium, where all forces acting upon it are in perfect balance and cancel themselves out. A free-body diagram is often used to represent a body and the forces acting upon it and helps us visualize the relationship of the vector forces. See this link: http://en.wikipedia.org/wiki/Free-body_diagram#Example
What does it mean to sat that the net force determines an objects acceleration?
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
When can forces be added together to find the net force upon an object?
Yes, when all the forces acting on a body have been resolved, the final force is known as the 'net force' acting on that body.
What is the relationship between and object's acceleration and the unbalanced force acting on it?
The acceleration plus other driving forces minus retarding forces equals the unbalanced force (force net.)
Which forces are unbalanced?
coz if they werent, whatever they were acting on, would either stay sill, or move at a constant speed
What is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
What occurs forces acting upon a body are not balanced?
The body accelerates.
What is net effect of two forces acting on a body?
Depe
What forces are acting on your body as you sit quietly in a classroom?
Gravity.
What forces act on a falling object?
The forces acting on a falling body are gravity and air resistance.
What is equilibrant forces?
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.
If a moving body has no acceleration does it mean no force acts on it?
There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.
How is force acting on a falling object?
1.a buoyant force acting on the body upwards due to air . 2.the weight of body acting downwards . this two forces acts.....
How forces affect speed?
The relationship is given by Newton's Second Law: F=ma F (force) is the net force - this refers to the vector sum of all forces acting on a body. m is the mass, and a the acceleration - the change of velocity.
What does the net force equal when three forces are acting on the same body and that body does not move?
zero
What are the different forces acting on a body immersed in a liquid?
2 forces act on a body when it is ... Weight&buoyant force
How many forces are acting on a body which is at rest?
In most cases, when a body is at rest, there are two forces acting on it: the force of gravity pulling downward and the normal force pushing upward. These forces are equal and opposite, resulting in a balanced or net force of zero.
