For linear motion.. is it true that a body will point in the direction of the resultant force?

This seems true to me because the I know that in circular motion, the object will fly from the point of tangency when released.

And the point of tangency for linear motion is in the direction of the motion....

Is this correct?

2nd question:

I added a picture of a lawn mower being pushed by force (P) and moving horizontally.

How would the vertical forces zero out, would this mean that the normal force is not equal to the weight force?
