Newton's Laws Flashcards
1
Q
what is inertia?
A
the tendency of an object that tells if to stay still or continue moving
2
Q
describe Newton’s second law
A
an object will move on the direction of an unbalanced force
3
Q
what is second law’s formula?
A
force(N) = mass(kg) X acceleration (m/s2)
4
Q
describe Newton’s third law
A
for every force there is another force in the opposite direction but with the same strength (every force comes in pairs)
5
Q
what is momentum?
A
is a property that tells how hard is to stop an object in motion
6
Q
describe Newton’s 1st law in your own words
A
when an object is in motion it will continue moving if an object is still it will continue still, until an unbalanced force acts on it
7
Q
momentum formula is….
A
P(momentum kgm/s) =
mass(kg) X velocity(m/s)
