Physics
A push or pull on an object.
Force
The pivot point of a lever.
Fulcrum
The path traveled by a moving object.
Trajectory
The scientist who discovered the Three Laws of Motion.
Isaac Newton
The study of how objects interact with each other and their environments.
Physics
The average location of weight in an object; aka an object’s balance point.
Center of Gravity
The amount of matter (or “stuff”) in an object.
Mass
The inward force felt by objects moving in circles.
Centripetal Force
The amount of force exerted on an object because of gravity. *NOT the same as mass.
Weight
A systematic way of solving problems
Engineering Design Process
A force of attraction between two objects.
Gravity
A simple machine with an arm and a fulcrum.
Lever
The resistance felt by one object moving across another.
Friction
An extension of Newton’s First Law of Inertia; states that the total momentum of a system stays constant unless acted on by an outside force.
Conservation of Momentum
The property of objects described by Newton’s First Law: objects in motion tend to stay in motion unless acted on by an outside force.
Inertia
The force from a stretched object.
Tension
