Momentum Flashcards
1
Q
Momentum
A
The product of an object’s mass and its velocity
2
Q
Linear momentum
A
A vector quantity with the same direction as the velocity of the object
3
Q
Newton’s second law of motion in terms of momentum
A
The resultant/ net force acting on an object is equal to the rate of change of momentum of the object in the direction of the resultant/ net force.
4
Q
Impulse
A
The product of the resultant/ net force acting on an object and the time the resultant/ net force acts on the object
5
Q
A closed /an isolated system
A
A system on which the resultant/net external force is zero
6
Q
State the principle of conservation of linear momentum
A
The total linear momentum of a closed system remains constant
7
Q
Projectile
A
An object upon which the only force acting is the force of gravity
