Physics
The science that deals with matter, energy, motion, and force
Force
A push or a pull
First
Newton's ____ law of motion states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force
Second
Newton's ____ law of motion states the acceleration of an object depends on the mass of the object and the amount of force applied.
Third
Newton's ____ law of motion states that for every action there is an equal and opposite reaction
Projectile
An object that is thrown or launched
Trajectory
The path a projectile follows
Meter
Unit of measurement equal to 100 centimeters
Angle
May affect the height of the trajectory or the distance the projectile may travel; 0, 45, 70, etc.
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
How far an object moves
Height
The measure of how tall something is or its distance from the floor
Marshmallow
Fluffy, sweet food that can be used as projectiles
Challenges
Includes distance, height, and accuracy
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
A thing used 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
Trebuchet
Worked like a giant slingshot and could propel object up to 980 feet.
Cannon
A big gun, especially one mounted on a base or wheels; used in our online simulation
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
Work
A result of a force moving an object a certain distance.
Friction
A force that opposes motion between two surfaces that are in contact
Fluid friction
Friction that occurs as an object moves through a fluid
Sliding friction
Friction that occurs when one solid surface slides over another
Rolling friction
Friction that occurs when an object rolls over a surface
Static friction
Friction that acts on objects that are not moving
