Physics 301 Module Five Quiz

What is the relationship between linear speed (v) and angular velocity (omega) in uniform circular motion?

• v = r - omega

• v = r + omega

• v = r * omega

• v = omega / r

What is the SI unit for angular velocity?

• Meters per second squared

• Radians per second squared

• Radians per second

• Meters per second

What is the direction of angular velocity when an object is rotating clockwise?

• Positive

• Negative

• Zero

• Depends on the radius

What is the formula for angular acceleration (alpha)?

• alpha = v * t

• alpha = r * omega

• alpha = v / r

• alpha = (omega final - omega initial) / t

What is the relationship between tangential acceleration (a_t) and angular acceleration (α)?

• a_t = α / r

• a_t = α - r

• a_t = α * r

• a_t = α + r

What is the unit for tangential acceleration?

• Radians per second

• Meters per second

• Radians per second squared

• Meters per second squared

What is kinematics concerned with in rotational motion?

• Description of motion with regard to force and mass

• Description of motion without regard to force and mass

• Description of force and mass without regard to motion

• Description of force and mass with regard to motion

What is the relationship between change in velocity (delta v) and change in angular velocity (delta omega) in rotational motion?

• delta v = r * delta omega

• delta v = delta omega / r

• delta v = r + delta omega

• delta v = r - delta omega

What is the direction of tangential acceleration in rotational motion?

• Depends on the radius

• Same as the direction of tangential velocity

• Opposite to the direction of tangential velocity

• Perpendicular to the direction of tangential velocity
