Need help with the following 5 questions for biomechanics

1. Which is not an acceptable representation of inertia?

L

A force due to gravity

Mass x Velocity

A quantity and direction of motion

2. Which term describes the angular equivalent of mass?

Center of Mass

linear distance from the COM to the AOR

Lower case "omega"

Moment of inertia

3. What happens when momentum is plotted as a function of position?

Momentum becomes out of phase behind position

Momentum and position achieve a positive linear correlation

Momentum becomes out of phase in front of position

Momentum and position maintain equivalent phase

4. Why does position (distance) have the greatest effect on angular momentum?

Because the magnitude of position is squared

Because position of the center of mass dictates the phase state

Because position is the determinant for the axis of rotation

Because the magnitude of position is the inverse of the center of mass

5. What happens to the total momentum of a given system if there is an absence of external forces?

It eventually loses momentum in proportion to its mass

It remains constant

It will lose force to other bodies within the system

it eventually loses momentum invers to the magnitude of its velocity
