1.5 - Newtons 1st & 2nd Laws Flashcards
1
Q
What is the first law of motion?
A
A resultant force is required to change the motion of an object
2
Q
What will happen if the resultant force is 0?
A
The object will continue with its motion
3
Q
What is the second law of motion?
A
Anything other than zero resultant force acts on an object, then it willl cause the object to accelerate. The size of the resultant force is directly proportional to the acceleration it causes.
4
Q
What is the formula for the resultant force?
A
Resultant Force = mass x acceleration (f=ma)
5
Q
What is the formula for acceleration?
A
force / mass = acceleration (f/m=a)
6
Q
A
