Question 1621

▼

How does the position vector r influence the calculation of torque?

It only affects mass
It reduces speed
It determines the moment arm and direction of torque
It changes time

Question 1622

▼

What is the relationship between the rate of change of angular momentum and applied torque?

Torque is half
They are unrelated
They are equal
Torque is negative

Question 1623

▼

Why is angular momentum a conserved quantity in isolated systems?

Because friction stops it
Because mass vanishes
Because there is no external torque to change it
Because time stops

Question 1624

▼

What is the consequence of violating one of the six equilibrium conditions in 3D?

Nothing happens
The body glows
The body will accelerate in the corresponding direction or axis
It changes color

Question 1625

▼

How does the principle of moments relate to rotational equilibrium?

Moments are irrelevant
All moments must be zero
The sum of clockwise moments equals the sum of counterclockwise moments
Moments add up to infinity
