There is a net net torque that is applied to a rigid object. What happens?
a. the angular momentum of the object will change
b. the kinetic energy of the object will change
c. the object will experience an angular acceleration
d. the rotational inertia of the object will change
e. a., b., and c.
I say c, am i close
a) is the correct answer.
c) is not necessarily correct because the torque can be at right angles to the angular moemntum, causing only the direction of the angular momentum vector to change and not its magnitude.
Yes, you are close! The correct answer is actually e) a., b., and c. When a net net torque is applied to a rigid object, several things happen:
a. The angular momentum of the object will change: Angular momentum is the product of rotational inertia and angular velocity. When a net torque is applied, it causes a change in the angular momentum, since torque is defined as the rate of change of angular momentum.
b. The kinetic energy of the object will change: Torque is also related to changes in kinetic energy. When a net torque acts on a rigid object, it can either add or subtract rotational kinetic energy from the object.
c. The object will experience an angular acceleration: Angular acceleration is a measure of how quickly an object's angular velocity changes. When a net torque is applied, it causes the object to accelerate or decelerate its rotation, resulting in an angular acceleration.
So, while option c is correct, options a and b are also true. Therefore, option e) a., b., and c. is the most accurate answer.
