Term

Definition
a measure of how an object resists changes in motion; it is a measure of an object’s mass 


Term

Definition
An object in motion/at rest will remain in motion/at rest unless acted on by an outside force. 


Term

Definition
an unbalanced force (or net force, S) causes an object to accelerate; this acceleration is directly proportional to the unbalanced force and inversely proportional to the object’s mass; called the law of acceleration
a = SF / m or S F = m a 


Term

Definition
When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for every action, there is an equal, but opposite reaction; called the law of actionreaction

Term
Momentum, definition and formula: 

Definition
a measure of how hard it is to stop a moving object; it is the product of the object's mass and its velocity; since velocity is a vector, momentum is a vector quantity; symbol is p and SI unit are kg m/sec. The direction of the momentum is the same as that of the velocity.
p= m v 


Term

Definition


Term
Definition and formula for impulse: 

Definition
a force exerted over a time interval; symbol is J and SI unit is N sec
J = F t 


Term
Impulse in relation to average force, mass and momentum.

Term
Law of Conservation of Momentum: 

Definition
the momentum of a closed, isolated system is constant; the sum of the initial momentum of the objects is equal to the sum of the final momentum of the objects
Σp_{i} = Σp_{f}
