## What is the relationship of force and length?

It is characterized by a positive slope (i.e. force is getting greater as length increases) at short lengths (the so-called ascending limb of the force-length relationship), a zero slope (the so-called plateau region) at intermediate lengths, and a negative slope (i.e. force decreases with increasing lengths; …

### What is the relationship between muscle length and muscle force tension )?

The length-tension (L-T) relationship of muscle basically describes the amount of tension that is produced by a muscle as a feature of it’s length. That is to say, when tested under isometric conditions, the maximal force produced or measured will be different as the muscle lengthens or shortens.

#### Why does active force vary with muscle length?

The change in the active force amount is completely caused by the amount of myosis bound to actin. The shorter the muscle’s resting length is, the more myosis filaments bind to actin filaments.

**What is the relation between resting muscle length and strength of contraction?**

As it turns out, the natural resting length of our skeletal muscles maximizes the ability of the muscle to contract when stimulated. If the resting length is shorter or longer, contraction is compromised.

**What is force per unit length?**

F/l is the force per unit length between two parallel currents I1 and I2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. The force exists whether the currents are in wires or not.

## What is the length of the force arm?

The arm of a force relative to a given point is the shortest distance from the point, or center, to the line of action of the force. In other words, it is the length of the perpendicular dropped from the point to the line of action of the force.

### Which of the following describes the relationship between length and tension?

Which of the following describes the relationship between length and tension? The active force can increase or decrease, depending on the starting resting length of the muscle. Why does the active force of skeletal muscle change with the muscle’s resting length?

#### Why is the force length relationship important?

The key feature of the length-tension relationship is the extra force that can be exerted during muscular contractions when the passive elements are able to contribute, which occurs when the muscle is elongated to long lengths during normal strength training, and also during eccentric training.

**What is the force length relationship of muscle?**

The force -length relationship indicates that muscles generate the greatest force when at their resting (ideal) length, and the least amount of force when shortened or stretched relative to the resting length.

**How is force affected by muscle length?**

## How do you find force per length?

The force per unit length can then be calculated using the known currents in the wires: Fl=(4π×10−7T⋅m/A)(5×10−3A)2(2π)(5×10−2m)=1×10−10N/m.

### What is the force per unit length between the two wires?

This force between two current carrying wires gives rise to the fundamental definition of the Ampère: If two long parallel wires 1 m apart each carry a current of 1 A, then the force per unit length on each wire is 2 x 10- 7 N/m.

#### What is the relationship between tension and length?

The length-tension relationship is the observation that single muscle fibers do not produce the same amount of isometric force when they are activated at different static lengths.

**What is the force relationship?**

Newton’s second law of motion defines force as the product of mass times ACCELERATION (vs. velocity). Since acceleration is the change in velocity divided by time, you can connect the two concepts with the following relationship: force = mass x (velocity / time) = (mass x velocity) / time = momentum / time

**What is the relationship between velocity and force?**

Force and velocity are connected concepts — one acts on the other. Force is a measure of power. It makes things happen. Velocity, on the other hand, is a quality an object has. Apply force to an object, and its velocity changes. This does not work the other way around — you cannot apply velocity to an object and change its force.

## What is length tension curve?

The isometric length-tension curve represents the force a muscle is capable of generating while held at a series of discrete lengths. When tension at each length is plotted against length, a relationship such as that shown below is obtained.
