Smart Choices and Constraints Exam

Front

What is drag in the context of vehicles?

Back

Drag is the resistance experienced by an object moving through a fluid (like air), which opposes its motion.

Front

How can aerodynamics affect a car's performance?

Back

Aerodynamics refers to how air flows around a vehicle. A well-designed aerodynamic shape reduces drag, improving speed and fuel efficiency.

Front

What is the main source of energy for Earth?

Back

The sun is the primary source of energy for Earth, providing light and heat that drive weather, photosynthesis, and other processes.

Front

What does it mean to consider constraints in problem-solving?

Back

Considering constraints means recognizing the limitations or restrictions that affect how a problem can be solved, such as time, resources, and rules.

Front

What is air resistance?

Back

Air resistance is a type of friction that occurs when an object moves through air, slowing it down.

Front

How can a streamlined design help reduce drag?

Back

A streamlined design minimizes the surface area that faces the direction of motion, allowing air to flow smoothly over the object and reducing drag.

Front

What is the relationship between speed and drag?

Back

As speed increases, drag also increases, making it more important to have an aerodynamic design at higher speeds.

Front

What is an example of a constraint in a project?

Back

A budget limit is a common constraint that restricts how much money can be spent on a project.

Front

Why is planning important in problem-solving?

Back

Planning helps identify steps to take, resources needed, and potential obstacles, leading to more effective solutions.

Front

What is the effect of surface roughness on drag?

Back

Rough surfaces increase drag by disrupting the smooth flow of air, leading to more turbulence.
