Answer:
the force that are included here is given as
1) Gravity
2) Friction
3) Applied force
Explanation:
As per the Force diagram of the moving block
We know that the block is moving with constant speed
so here the applied force on the block is counter balanced by the friction force due to ground
Also we can see that the the Normal force due to ground is also counter balanced by the weight or force of gravity on it
So the force that are included here is given as
1) Gravity
2) Friction
3) Applied force
