Question

what is cause of motion in a rigid object​

Answer 1

Answer:

When a solid object or surface is subjected to dynamic and mechanical forces, and thermal effect, the imbalance of the net forces can cause the body to move and deform. A solid object is often considered as a rigid body in flow simulations.

Explanation:

Answer 2

Answer:

When a solid object or surface is subjected to dynamic and mechanical forces, and thermal effect, the imbalance of the net forces can cause the body to move and deform. ... In equation 2.427, is the moment of inertia; ⃗ is the angular velocity; and ⃗ is the total/net torque acted on the rotating body.
