P2.2.4 - Newton's Second Law Flashcards
1
Q
What 3 things can a resultant force do?
A
Change the speed of an object
Change the direction of motion of an object
Change both the speed and direction of motion
2
Q
What is Newton’s second law?
A
The acceleration that the resultant force produces depends on:
The size of the resultant force
The mass (inertia) of an object
3
Q
What is the equation relating to Newton’s second law?
A
Force(N) = mass(kg) x acceleration(m/s^2)
4
Q
What is 1N equal to?
A
1N = 1Kg m/s^2
