# Does impulse depend on mass?

## Does impulse depend on mass?

This will give us a new concept called “impulse”. Just as we had defined kinetic energy, we will define a new quantity called momentum which will depend on the mass and velocity of the body. We will then see that impulse on a particle will be the change in momentum, just as work was equal to change in kinetic energy.

### What does impulse depend on?

Impulse also depends on how long the force is applied. More time, more impulse. So, the impulse exerted on an object depends directly on both how much force is applied and for how long the force is applied. Impulse is the product of the force and the time.

#### What two factors affect the impulse?

The two main factors are insulation by the myelin sheath and the diameter of the axon.

Why does bouncing increase impulse?

Bouncing is a way to increase impulse. Because an object that bounces changes directions the force of impulse must be absorbed then generated by the target object. In the absence of an external force, the momentum of a system remains unchanged.

How does impulse increase?

An object’s change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it’s the increase or decrease of an object’s momentum. As you decrease the time of the impulse, the force increases.

## How does mass affect momentum quizlet?

Mass and velocity and how it affects an object’s momentum. When the mass is greater (at the same speeds), the momentum is greater. An object with a very small mass that has a lot of momentum because it is moving very quickly. The momentum of an object, or set of objects (system), remains the same if it is left alone.

### What affects speed of impulse?

Factors such as speed of diffusion are affected by temperature. Sodium ions diffuse into the axon, and potassium ions diffuse out more quickly, and ion channels open faster. Velocity of nervous impulses increases linearly with temperature, within the normal range (0-40 +? ° C).
