If the coefficient of restitution of a collision is 0, then the collision will be (a) perfectly elastic, (b) inelastic, (c) perfectly plastic, (d) none. For a perfectly inelastic c... If the coefficient of restitution of a collision is 0, then the collision will be (a) perfectly elastic, (b) inelastic, (c) perfectly plastic, (d) none. For a perfectly inelastic collision, e= (a) 0, (b) less than 1, (c) more than 1. If an object continuously changes its position, it is said to be in ______.
Understand the Problem
The question is asking about the principles of collision in physics, specifically regarding the coefficient of restitution, types of collisions, and the state of an object in motion.
Answer
(c) perfectly plastic, (a) 0, Motion
The final answer is: 7. (c) perfectly plastic, 8. (a) 0, 9. Motion
Answer for screen readers
The final answer is: 7. (c) perfectly plastic, 8. (a) 0, 9. Motion
More Information
The coefficient of restitution (e) measures elasticity in collisions. If e = 0, the collision is perfectly inelastic, often synonymously referred to as perfectly plastic, meaning the objects do not separate. Continuous position change typically indicates motion.
Tips
Avoid confusing perfectly inelastic (e=0) with inelastic (0<e<1). In completely inelastic, objects do not rebound.
