Newton Flashcards
1
Q
First law
A
A resultant force is required to change the motion of an object
Eg stationary object RF = 0 it stays stationary
Moving object RF = 0 it’s stays at the same velocity
2
Q
Second Law
A
If a non zero resultant force acts on an object then it’ll cause the object to accelerate
3
Q
Second law equation
A
Resultant force = mass x acceleration
4
Q
Inertial mass and it’s equation
A
How difficult it is to change an objects velocity
Force
____________
Acceleration
5
Q
Third law
A
When two objects interact the forces they exert on each other are equal and opposite
6
Q
What does the equal and opposite refer to in Newton’s third law
A
Equal ~ magnitude
Opposite ~ direction
