4th
Where is the fulcrum for levers on the human body located?
Muscles
Bones
Joints

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 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
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
Standing on your toes is an example of what lever
1st class
2nd class
3rd class
What law best describes the action when a high jumper is pushing off the ground before the jump?
Newton's 1st law (inertia)
Newton's 2nd law (acceleration)
Newton's 3rd law (reaction)
What class lever occurs at the neck when nodding your head
1st class
2nd class
3rd class
What class lever is the arm using when a dart thrower is holding a dart up getting ready to throw?
1st class
2nd class
3rd class
