Term

Definition
distance traveled in a particular direction (change in position) 


Term

Definition
rate of change of displacement 


Term

Definition
rate of change of distance 


Term

Definition
rate of change of velocity 


Term
Newton's First Law of Motion 

Definition
An object at rest remains at rest and an object in motion remains in motion at a constant speed in a straight line unless acted on by an unbalanced force. 


Term
Newton's Second Law of Motion 

Definition
An unbalanced force will cause an object to accelerate in the direction of the net force. The acceleration of the object is proportional to the net force and inversely proportional to its mass. (Fnet = ma or Fnet = Δ p/Δ t (net force = rate of change of momentum)) 


Term
Newton's Third Law of Motion 

Definition
When two bodies A and B interact (push or pull), the force that A exerts on B is equal and opposite to the force that B exerts on A. 


Term
Translational Equilibrium 

Definition
net force acting on a body is zero 


Term

Definition
product of mass and velocity 


Term

Definition


Term
*Law of Conservation of Linear Momentum 

Definition
The total momentum of an isolated system (no external forces) remains constant. 


Term

Definition
The product of a force on an object and the displacement of the object in the direction of the force. 


Term

Definition
product of ½ times the mass of an object times the square of an object’s speed 


Term
Change in Gravitational Potential Energy 

Definition
product of an object’s mass times the gravitational field strength times the change in height 


Term
*Principle of Conservation of Energy 

Definition
The total energy of an isolated system (no external forces) remains constant. (OR – Energy can be neither created nor destroyed but only transformed from one form to another or transferred from one object to another.) 


Term

Definition
a collision in which both momentum and kinetic energy are conserved 


Term

Definition
a collision in which momentum is conserved but kinetic energy is not conserved 


Term

Definition
The rate at which work is done or the rate at which energy is transferred. 


Term

Definition
The ratio of the useful energy (or power or work) output to the total energy (or power or work) input. 


Term

Definition
The acceleration due to changing velocity direction. It points toward the center of the circular path and equals. 


Term

Definition
The name of any force or resultant of individual forces that points toward the center of a circular path.
