Do you know anything about biomechanics? Biomechanics is the research of structure, function, and motion of the biological system's mechanical characteristics, at any level from entire organisms to organs, cells, and cell organelles use the system of mechanics. Biomechanics falls under the umbrella of biophysics, which is a little bit different. Biomechanics can be applied to describe how muscles, bones, and joints react under certain conditions. Test your knowledge of biomechanics with this quiz.
The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.
The branch of mechanics that is concerned with the effects of forces on the motion of a body or system of bodies, especially of forces that do not originate within the system itself.
The study of the motion of a body or a system of bodies with consideration given to its mass or the forces acting on it.
If the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s.

The air travels more underneath the wing than above it. This creates higher pressure above the wing than below and lift is created.
The air travels more over the top of the wing than beneath it. This creates higher pressure below the wing than above it and lift is created.

Rate this question:
A fluid will exert an upward force on an object immersed in it equal to the weight of the fluid displaced by the object.
An object will float if it is lighter than the fluid it is immersed in.
When surface tension is in equilibrium with the downward force applied by the immersed object.
Rate this question:
A body will continue in a state of rest of uniform velocity unless acted upon by an external force.
For every action there is an equal and opposite reaction.
A body moves in a circle about a point called the axis of rotation.
The acceleration of an object is directly proportional to the force causing it and is inversely proportional to the mass of the object.
