The engineers created a m (a)   (simple model with no internal elements) of the vehicle for testing it in a wind tunnel.

1. The pendulum's o (a)   (swing) was measured to understand its movement pattern.

1. The temperature outside is a v (a)   (zmienna) that affects how I dress.

1. The d (a)   (the force of the air that acts against the movement of an aircraft or other vehicle) from the wind slowed down the airplane.

1. The v (a)   (speed) of the car increased as it went downhill.

1. C (a)   on the old metal gate made it rusty and weak.

1. His study habits were c (a)   (always behaving in the same way); he always studied for an hour every evening.

1. Switching off lights when not in use is an e (a)   (wydajny) way to save energy.

CFD stands for computational (a)   dynamics.

1. A piece of machinery on which the wheels of a vehicle can ride in order to test how well the vehicle works under road conditions that are created artificially.

2. The car's performance was tested on the (a)   road to check its speed and efficiency.

1. Understanding the f (a)   (movement) of air around an object helps in designing aerodynamic vehicles.

1. Scientists use a w (a)   tunnel to study how objects behave in different air speeds.

1. We need to narrow (a)   our options before making a decision.

1. The b (a)   of a turbine spin to generate electricity.

1. R (a)   concrete is used in building construction for added strength.

1. Engineers (a)   out tests to ensure the safety of the bridge.

1. Scientists use experiments to d (a)   (ustalić, określić) the effects of different variables.

1. Metal can r (a)   (corrode) if it's exposed to moisture for too long.

1. Researchers v (a)   (to prove that something is true) their findings by repeating experiments for accuracy.

Comparing two similar items or systems directly against each other to see which one performs better or meets certain criteria is called b (a)   testing.

The tall structure that supports the blades of a wind turbine is called the t (a)  

Conducting experiments or assessments in real-world environments rather than in controlled laboratory settings is called f (a)   testing.

A test or practice attempt to evaluate the performance or functionality of something before it is used or implemented on a larger scale is called a t (a)   run.

A preliminary version or model of a product, often built to test or demonstrate its design and functionality before full-scale production is called a p (a)
