IAPS Force and Motion Key Science Vocabulary Flashcards
Someone who uses science and tools to build a product that solves a practical problem.
Engineer
The rate at which an object moves, equal to the distance traveled per time interval.
Speed
A quantity that describes both speed and direction.
Velocity
The total distance an object travels divided by the amount of time it took the object to travel that distance.
Average Speed
The energy an object has because of its motion.
Kinetic Energy
Something that happens in a repeated and predictable way.
Pattern
To change speed and/ or direction per unit time.
Accelerate
When the magnitude and direction of more than one force acting on an object results in zero net force.
Balanced Force
A push or a pull.
Force
When the magnitude and direction of more than one force acting on an object give a net force unequal to zero.
Unbalanced Force
The combined force (magnitude and direction) acting on an object.
Net Force
The change in speed and/ or direction per unit time.
Acceleration
The SI unit of measurement for force.
Newton (N)
A property of matter by which it remains at rest or in unchanging motion unless acted on by some external force.
Inertia
A force that exists at the boundary between any two pieces of matter that are in contact with each other.
Friction
In engineering design, some - thing that limits the solution to a problem.
Constraint
A minimum requirement for how the design must function.
Criteria
A group of interacting objects or processes. Every system includes components, interactions, and boundaries.
System
The distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop.
Braking Distance
The distance a car travels during the reaction time.
Reaction Distance
The time interval between the moment a driver realizes a problem and when the driver applies the brakes.
Reaction Time
The total distance a vehicle travels during the driver’s effort to bring the vehicle to a halt; distance traveled during the driver’s reaction time plus the braking distance.
Stopping Distance
