Physics
The study of matter and energy and the interactions between the two through forces and motion.
Force
A push or a pull
Projectile
An object that is thrown or launched
Trajectory
The path a projectile follows
Speed
The distance an object travels per unit of time, such as meters per second
Mass
A measure of the amount of matter in an object
Distance
Challenge to determine how far a projectiles travels
Height
The measure of how tall something is or its distance from the floor
Marshmallow
Fluffy, sweet food that can be used as projectiles
Accuracy
A description of how close your projectile lands to a specific target
Consistency
The ability to repeat a task with little variation
Modification
Making changes to a device in hopes of improving it
Mousetrap
Designed to catch mice, but also used to create a device that can launch a marshmallow
Catapult
A device for hurling objects, such as launchers for marshmallows
Motion
An object's change in position relative to a reference point.
Constraints
Limitations or restraints, such as amount of available materials, time limits, and human capabilities
Data
information gathered during an experiment or from observations
Criteria
A test by which something can be judged or what your device is expected to be able to do
Engineering
The application of scientific knowledge for practical purposes
Gravity
A force that pulls objects toward each other
Air resistance
Fluid friction acting on an object moving through the air; also referred to as drag
Define
First step in the engineering design process involving the what, who, and why of a problem
Identify
Second step in the engineering design process involving constraints and criteria
Brainstorm
Third step in the engineering design process in which you think of multiple solutions for a problem
Select
Fourth step in the engineering design process in which you choose the most promising solution
Prototype
Fifth step in the engineering design process in which you develop a device or solution to address a problem
Test
Sixth step in the engineering design process in which you gather data and evaluate your prototype
Iterate
Seventh step in the engineering design process in which you get feedback from others to improve your design/solution
Communicate
Last step in the engineering design process in which your share your results or solution
Evaluate
Using data from tests will help you _____ your prototyype
Weight
A measure of the force of gravity on an object; changes with changes in gravity
Acceleration
A change in speed or direction
Kinetic
Energy of motion
Potential
Stored energy
Elastic
Type of potential energy stored in a rubberband or spring
Mechanical
Type of kinetic energy observed in the movement of the mousetrap's arm/hammer
Gravitational
Type of potential energy where due to an object's mass, its height off the ground, and gravitational acceleration
Terminal
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
Chemical
Type of potential stored in chemical bonds
Magnetic
Type of potential energy of the position of one magnet relative to another
