Define force
What is a push or a pull.
100
when an object is at rest it remains at rest, or if the object is moving it continues moving in a straight line with a constant speed
What is Newton’s First Law Of Motion
100
The density equation
What is Density= Mass (g)/Volume (cm cubed)
100
Define Buoyant Force
What is the upward force on an object in a fluid
200
A vector that describes speed and direction
What is velocity
200
Define balanced forces, unbalanced forces, and net force
What is... Net Force-all forces acting on an object Unbalanced Forces-when the net force is not zero Balanced Force-when the net force is zero
200
the acceleration of an object equals the net force divided by the objects mass
What is Newtons Second Law Of Motion
200
Definition of pressure
What is the force per unit of area applied on the surface of an object
200
the buoyant force on an object is equal to the weight of the fluid the object displaces
What is Archimedes Principle
300
The difference between Average speed and instantaneous speed
What is the average speed and the speed taken at a certain time.
300
all objects with mass are attracted to each other
What is the universal law of gravitation
300
when one object exerts a force on a second object, the second objects exerts an equal force in the opposite direction
What is Newtons Third Law Of Motion
300
the equation for pressure
What is Pressure=Force (newtons)/Area (meters squared)
300

400
The difference between speed and acceleration
What is the rate of change of distance with time. What is the rate at which velocity changes with time.
400
Centripetal Force
What is the force that is perpendicular to the velocity and toward the center of the circle
400
Equation for finding acceleration
