CO2 Dragster Design Study Guide

Force- is a push or pull when energy is applied to an object.

Friction- is another enemy of acceleration and speed.

Rolling friction-occurs when one surface roles over another.

Sliding friction- occurs when one surface slides over another.

Fluid friction- occurs when an object moves through a fluid, such as air or water.

Drag-is the force of air on a moving object; it has 2 components;what are they?

Frontal pressure and Rear Suction

Aerodynamics- the study of how solid objects displace fluid air and other gases.

Wind Tunnel- is the machine that calculates the drag of our dragsters.

Newton’s First Law of Motion- Inertia Law- a property of matter by which it remains at rest or in uniform motion unless that state is changed by some external force.

Newton’s Second Law of Motion- also known as f= ma. Thus, heavier objects require moreeffort to move at the same speed or distance as a lighter object.

Newton’s Third Law of Motion-states that for every action (or force) there is an equal reaction (or opposing force) in the opposite direction.

Engineering Design Process-linear process by which we constructed our dragster.

Specifications- are a given set of rules or limits you used to design your dragster.

What elementsstand out when talking about designing a successful dragster?

Weight, Friction (Fluid, Rolling), Specifications, Appearance

Advertising Vocabulary
