can someone please define the following for me?

Question

Terminal Velocity
Streamline/Aerodynamic
Resultant Force

thanks, i have got an exam tomorrow and i cannot find what these terms mean in my revision notes.

Answer 1

Terminal velocity is the constantly velocity of a falling object. An object initially falls under gravitational acceleration, but air resistance increases linearally with speed. As a result, a falling object eventually reaches a maximum speed where gravity and air resistance cancel each other out and the net force is zero, resulting in constant velocity.

Streamlined or aerodynamic, in this instance, probably refers specifically to a shape that has less drag as it moves through a fluid.

Resultant force is just the vector sum of two or more forces. In the case of terminal velocity, the resultant force of gravity and air resistance is zero.

Answer 2

Means Speed

Answer 3

well if you want to know the definitions look them up in a dictionary~~~~~~!!!!!!!! if you cant find one do to the library
