Newton's Laws of Motion Flashcards
1
Q
State Newton’s First Law
A
An object will remain at rest or at constant velocity unless acted upon by an external net force
2
Q
State Newton’s Second Law
A
The net force acting on an object is directly proportional to the rate of change of momentum and takes place in the direction of the force
3
Q
State Newton’s Third Law
A
When two objects interact, the force acting on one of the objects is equal but opposite to the force acting on the other object
4
Q
define linear momentum
A
Mass x Velocity
5
Q
Force =
A
(mv - mu) / t
6
Q
Why is F=ma a special case?
A
Can only be used when mass and acceleration are constant
7
Q
Define impulse
A
Change of momentum
8
Q
Area under a force/time graph =
A
Impulse
