When two forces P and Q acting along the same line then its resultant?

In that case, the resultant will either be the sum or the difference of the two forces (if they act in the same direction) or their difference (if they act in opposite directions).

What will you get if you draw lines of action of all the forces acting on the board annd extend the line?

What are two balanced forces?
Two balanced forces are two forces in equal magnitude acting on opposite directions along the same line of action. This is analogous to a tug-of-war where the two teams have the exact same pulling power.
Why does acceleration increase?
When many forces acting on the body then in the line of action of resultant forces of all applied forces, acceleration is produced.And if the value of resultant force increase with time then acceleration.a = FNET/mass of bodyOR,If change of momentum of body increases with respect to time then acceleration increase.a = ( mv-mu )/ twhere:-a=acceleration of bodym=mass of bodyu=initial velocity of bodyv=final velocity of bodyt=time taken to increase the velocity of body from u to v
What forces act on a frictionless air puck as it moves across a table in a straight line?
The force of air from the airholes on the puck, and the resultant force. A shear force (v). Velocity and acceleration forces, as well as gravity.
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.

An object is traveling in a straight line in space no forces are acting on the object based on this evidence what will happen to the objects motion?
Nothing will happen to the object's motion, it will continue along its path.
Why does acceleration increase?
When many forces acting on the body then in the line of action of resultant forces of all applied forces, acceleration is produced.And if the value of resultant force increase with time then acceleration.a = FNET/mass of bodyOR,If change of momentum of body increases with respect to time then acceleration increase.a = ( mv-mu )/ twhere:-a=acceleration of bodym=mass of bodyu=initial velocity of bodyv=final velocity of bodyt=time taken to increase the velocity of body from u to v
What are equal forces acting on an object in opposite directions?
Equal forces acting on an object in opposite directions are called balanced forces. If they are on the same line of action, they are called couple forces.
Can a sphere roll in a straight line?
On a smooth level surface, and with no forces acting on it after the moment of release, it MUST.
Why force have cosine value?
If a force is acting at an angle to the direction of motion then it is usually helpful to study components of the force along the line of motion and at right angles to it. For a force of magnitude f, acting at an angle x with the line of motion, the component along that line is f*cos(x).
What forces act on a frictionless air puck as it moves across a table in a straight line?
The force of air from the airholes on the puck, and the resultant force. A shear force (v). Velocity and acceleration forces, as well as gravity.
Can three vectors not in one plane give zero resultant?
No. For three vectors they must all lie in the same plane. Consider 2 vectors first. For them to resolve to zero, they must be in opposite direction and equal magnitude. So they will lie along the same line. For 3 vectors: take two of them. Any two vectors will lie in the same plane, and their resultant vector will also lie in that plane. Find the resultant of the first two vectors, and the third vector must be along the same line (equal magnitude, opposite direction), in order to result to zero. Since the third vector is along the same line as the resultant vector of the first two, then it must be in the same plane as the resultant of the first two. Therefore it lies in the same plane as the first two.
Does an object moving in a constant speed in a straight line have any forces acting on it?
It will have zero force BUT, it WILL have a constant velocity
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.
