Forces acting on a body are said to be balanced if

When a deforming force acts on a body. It undergoes change in its __.

What happens when force acting on an object are in opposite direction and equal?

The vector sum of a system of non-collinear forces acting on a rigid body is gives to be non-zero. If the vector sum of all the torques due to the system of forces about a certain point is found to be zero, does this mean that it is necessarily zero about any arbitrary point?

Explain with an example force can change the speed of an object.
