P2.2.3 - Newton's First Law Flashcards
1
Q
What is Newton’s First law?
A
An object will continue to stay at rest or move with uniform velocity unless a force acts on it
2
Q
What is the inertia of an object?
A
How difficult it is to change the velocity of an object
3
Q
What is the principle of inertia?
A
Moving objects keep moving and objects that are stationary do not move
4
Q
Why do objects continue to move at a steady speed?
A
There is no resultant force so the object doesn’t accelerate or decelerate
5
Q
What is equilibrium?
A
When the resultant force is zero
