Question 216

▼

How does the kinetic energy expression separate for a system of particles?

K = K' + V
K = K' + (1/2)MV²
K = (1/2)MV² only
K = K' + M²V

It stops suddenly
It accelerates randomly
It continues with the same velocity
It disappears

Question 218

▼

What is the primary factor in determining torque effectiveness?

Parallel component of force
Mass of object
Perpendicular component of force
Color of the object

Question 219

▼

How is angular momentum conserved in a system?

By increasing external torque
By stopping all motion
By redistribution among parts when no external torque acts
By changing mass

Question 220

▼

What is the condition for zero gravitational torque on a body?

When mass is zero
When gravity is zero
When supported at the center of gravity
When angular velocity is zero
