Force - Newton's Laws Flashcards
1
Q
What is Newton’s First Law?
A
An object in motion stays in motion and an object at rest stays at rest unless acted upon by a net force.
2
Q
What is the tendency of an object to maintain its state of motion called?
A
Inertia
3
Q
What is inertia a measure of?
A
Mass
4
Q
What is Newton’s Second Law?
A
Net force causes acceleration.
5
Q
What is acceleration directly proportional to?
A
Net force
6
Q
What is acceleration inversely proportional to?
A
Mass
7
Q
What is the equation for Newton’s Second Law?
A
F = ma or a = F/m
8
Q
What is Newton’s Third Law?
A
For every force, there is an equal and opposite force?
9
Q
What must the action/reaction pair act on in Newton’s Third Law?
A
The same objects
10
Q
What is different about the two forces in Newton’s Third Law?
A
