What is newtons first law?
An object will stay at rest unless a force acts upon it
Newtons second law
F=ma
What is the force equation
Force=mass x acceleration
What is work?
Mechanical energy required to move
What is the work equation?
Work= force x distance
What is power?
The amount of work over a given amount of time
What is the power equation?
Power = work/time
What is efficiency?
A measure of how much energy actually goes into the movement
What is the efficiency equation?
Efficiency = energy in/energy out
How do muscles work?
by shortening
What is striated muscle?
A muscle made of sarcromeres with a striped appearance
What is myosin?
A protein known for its role in muscle contraction with two heads and a long tail
Where is myosin found?
Myosin creates thick filament
What forms thin filament?
Actin and tropomyosin
What is a fascicle?
