What is mechanical forces?
The force exerted by a machine is called a mechanical force
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What is example of a mechanical wave Apex?
A wave generated by a machine
What type of advantage described the ability of a machine to increase output force?
Mechanical advantage is the greater outputted force than inputted force that is generated by using a machine. One example is pulling a pulley to create a much greater output force on the other side that a person could not lift without a pulley.
What is the mechanical force of muscle contraction is generated by?
The mechanical force of muscle contraction is generated by a sliding of thin filaments past thick ones.
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
How is chemical and mechanical energy the same?
Chemical energy appears as heat, such as burning coal with oxygen.Mechanical energy is the result of a force being generated
How hydrostatic pressure is generated in the heart?
Hydrostatic pressure is generated by the systole (contraction of the ventricles).
Is the hydrogen bomb a source of mechanical energy?
Any explosion is an example of mechanical engery even though it is initiated by a chemical or nuclearreaction. The explanding gases generated by the initial reaction exerts a force that destroys buildings and such.
What is a Mechanical advantage equal to?
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
What happens in the heart when an action potential is generated in the SA node?
Myocardial contraction

A contraction in which a muscle exerts force lengthens and is overcome by a resistance?
Eccentric contraction (isotonic)
