Forces Flashcards
1
Q
define inertia
A
how difficult it is to change the velocity of an object
2
Q
How to calculate inertia
A
M = F/a
3
Q
what is newtons first law
A
If the forces acting on a body are balenced resultant force is 0 so the object carries on doing what its doing
if stationary remains stationary
4
Q
What is newtons 2nd law
A
if the forces on a body are not resultant object slows or speed up
f = ma / a = f/m
5
Q
what is newtons third law
A
equilibrium means the resultant force is 0
every action has an equal and opposite reaction
