Inertia and Newton's third law Flashcards
(4 cards)
1
Q
What is Inertia?
A
The tendency to keep moving with the same velocity.
2
Q
An objects interial mass measures…
A
how difficult it is to change the velocity of an object.
3
Q
How can Inertial mass be found?
A
Using Newton’s second law of F = ma
Rearrange to m = F/a, so inertial mass is just ratio of force over acceleration.
4
Q
What does Newton’s third law say?
A
When 2 objects interact, the forces they exert on each other are equal and opposite.
