For a perfectly inelastic collision, e = ? If an object continuously changes its position, it is said to be in ? In mathematical form, torque or moment of force is given by ?
Understand the Problem
The question is asking about concepts related to physics, specifically about perfectly inelastic collisions, continuous change in position, and torque or moment of force. This involves understanding energy conservation during collisions and the principles of rotational dynamics.
Answer
e = 0, in motion, \( \vec{r} \times \vec{F} \)
The final answer is e = 0, it is said to be in motion, and torque is given by ( \vec{r} \times \vec{F} ).
Answer for screen readers
The final answer is e = 0, it is said to be in motion, and torque is given by ( \vec{r} \times \vec{F} ).
More Information
For a perfectly inelastic collision, the coefficient of restitution is zero, meaning kinetic energy is not conserved, and objects stick together. Torque is the cross product of position vector and force.
Tips
A common mistake is confusing torque with a simple multiplication of position and force, rather than considering the vector cross product.
