What is the correct definition of Newton's Law of Inertia
The acceleration of a body is proportional to, and in the same direction as, the unbalanced force applied to it
An object either remains at rest or continues to move at a constant velocity, unless acted upon by a some external force
For every action there is an equal and opposite reaction
a 2nd Class Lever has what in the middle
Fulcrum
Effort/force
Resistance/weight
What is the equation used in Newton's law of acceleration?
a = f x m
f = m x a
m = f x a
What is Newton's First Law also known as?
The law of reaction
The law of inertia
The law of acceleration
For a first class level, the fulcrum is placed
Between the effort/force and resistance/weight
Effort/force in the middle with fulcrum on one end and resistance/weight on the other
Resistance/weight in the middle with fulcrum and effort/force on the ends
Using Newton's formula for acceleration, how much mass does an object have if its acceleration is 80 m/s and the force applied was 24N
19.2 kg
0.3 kg
30 g
