The critical factor that determines the force of a heartbeat is the degree of stretch of the cardiac muscle just before it contracts. The force of the heart beat can also be called the stroke.
The batter swinging the bat.
Yes, an equal and opposite force.
The size of the normal force and coefficient of friction determines the size of frictional force.
The size of the normal force and coefficient of friction determines the size of frictional force.
That is called gravity.
A push or a pull determines the force between the two objects
Buoyancy force.
