# Balloon Car Vocab

### Aerodynamic Motion Vocab

TermDefinition
The rate at which velocity (speed and direction) changes in an object Acceleration
The study of forces and how easily objects move through the air. Aerodynamics
Equal forces acting on an object in opposite directions Balanced Forces
Outside of car or the part that the passengers sit inside when driving Car Body
A decrease in speed (slowing down) Deceleration
A path which someone or something moves. Direction
A force that opposes the motion of an object (usually in the opposite direction of thrust) Drag Force
The ability to do work or cause change Energy
Vent that releases fuel from the engine to the rear of the vehicle to be released. Exhaust System
A push or pull exerted on an object Force
The resistance that one surface or object encounters when moving over another (usually slows motion) Friction
The tendency of an object to resist/avoid a change in its motion Inertia
A measure of the amount of matter in an object Mass
The force or speed with which something moves Momentum
An object's change in position relative to a reference point (starting point) Motion
LAW OF INTERTIA An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's First Law
FORMULA LAW Force = mass x acceleration Newton's Second Law
ACTION/REACTION LAW For every action force there is an equal and opposite reaction force Newton's Third Law
The energy needed to make objects move Power Source (Fuel)
A set of parts that produces a force to make an object move forward Propulsion System
Distance traveled per unit time Speed
A force that PUSHES an object forward Thrust Force
A force that causes an object to change its motion Unbalanced Forces
The speed of an object in a particular direction Velocity
A machine made up of a wheel that turns on a center bar Wheels and Axles
Force exerted on an object that causes it to move Work
Energy that is stored and waiting to be used Potential Energy
Energy of Motion Kinetic Energy

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
