The relation between the moment of inertia I, torque τ and angular acceleration α is given by:
Correct answer: C. τ = I α
- A. τ = I2α
- B. I = τ α
- C. τ = I α
- D. α = τ I
Explanation
Explanation:The correct formula relating torque (τ), moment of inertia (I), and angular acceleration (α) is τ = I α. This equation shows that torque is equal to the product of moment of inertia and angular acceleration. The other options either incorrectly square the moment of inertia, switch the positions of the variables, or incorrectly multiply torque and moment of inertia. Understanding the correct relationship between these variables is crucial in solving problems involving rotational motion.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
