Units and dimensions — SI unit of angular acceleration Identify the correct SI unit for angular acceleration (rate of change of angular velocity). Choose the correct option.

Q: Units and dimensions — SI unit of angular acceleration Identify the correct SI unit for angular acceleration (rate of change of angular velocity). Choose the correct option.

Concept Angular acceleration α = dω/dt. Angular velocity ω is in rad/s, so α is in rad/s2. Why the others are wrong N·m is torque (unit of moment). m/s is linear velocity. m/s2 is linear acceleration. Final Answer rad/s2

Difficulty: Easy

N-m
m/s
m/s2
rad/s2

Correct Answer: rad/s2

Explanation:

Concept
Angular acceleration α = dω/dt. Angular velocity ω is in rad/s, so α is in rad/s².

Why the others are wrong

N·m is torque (unit of moment).
m/s is linear velocity.
m/s² is linear acceleration.

Final Answer
rad/s2

Projectile on an upward inclined plane — time of flight expression Given: initial speed u, angle of projection α with the horizontal, and an upward plane inclination β with the horizontal. Select the correct formula for the time of flight (until the projectile strikes the plane).
Projectile motion on inclined planes: Compare the range on a downward slope versus an upward slope for identical launch parameters. Conditions: Same initial speed (u) and same launch angle (α) with respect to the horizontal; magnitude of plane inclination (|β|) is the same in both cases. Choose the correct comparative statement about the range measured along the plane.
