ROTATIONAL MOTION

What determines the direction of the cross product of two vectors?

• Left-hand rule
• Smaller vector direction
• Sum of vector directions
• Right-hand rule

In the equation v = ω × r, what does r represent?

• Distance from Earth's center
• Radial acceleration vector
• Tangential displacement
• Position vector from the fixed axis or point to the particle

What is the formula for linear velocity of a particle in a rotating rigid body?

• v = ω + r
• v = ω · r
• v = ω/r
• v = ω × r

What is the magnitude of angular velocity in rotational motion?

• v/r²
• a/r
• F/mr
• ω = dθ/dt

How is the direction of angular velocity determined in rotational motion?

• Left-hand rule
• Direction of linear velocity
• Tangential to the path
• Using the right-hand rule
