Newton's Laws of Motion Flashcards
1
Q
What is Newton’s 1st law? What is it also known as?
A
Law of Inertia
Objects are stationary or moving at a constant velocity unless acted on by an external object
2
Q
What is Newton’s 2nd law? What is the equation?
A
Force acting on an object is directly proportional to its mass and acceleration
F = ma
3
Q
What is Newton’s 3rd law?
A
Every action has its equal opposite reaction
4
Q
What is the equation for the moment of inertia on rotating objects?
A
I = m x r^2
Moment of inertia = mass x axis of rotation^2
5
Q
What is the equation for weight?
A
W = m x g
weight = mass x gravity
6
Q
What is gravity on Earth?
A
9.81 m/s ^2
