Sentence construction

Hello,

1. A force acting on an object perpendicular to the surface of the object is called thrust.

I am not able to understand this construction.

Could any one explain it?

Thanks.

Could any one explain it? I am not sure what bothers you. The simple subject and predicate are: A force is called thrust.

A force [which is] acting on an object [that is] perpendicular to the surface of the object is called thrust.

"that " refers back to the object or the force.

Thanks.

Hello,


A force [which is] acting on an object [that is] perpendicular to the surface of the object is called thrust.

Is it correct If I use "which is" in place of "that is" in the above sentence?

Thanks.
