Answer
The best characteristics to show that the energy of each marble changed during and after the collision are speed and location.
Solution
To determine which two characteristics of the marbles would best show that the energy of each marble changed during and after the collision, we need to consider the factors that directly relate to the energy of the marbles.
-
Kinetic Energy: The kinetic energy of an object is given by the formula
, where is the mass and is the speed of the object. Therefore, changes in speed will directly affect the kinetic energy. -
Mass: While mass is a factor in the kinetic energy formula, if the marbles are identical, their mass will not change during the collision. Thus, mass alone would not show a change in energy.
-
Shape: The shape of the marbles does not directly affect their kinetic energy in a straightforward manner during a collision.
-
Location: The location of the marbles does not provide information about their energy changes during the collision.
Given this analysis, the best characteristics to show that the energy of each marble changed during and after the collision would be:
- Speed: Changes in speed will directly indicate changes in kinetic energy.
- Location: While not directly related to energy, observing the location before and after the collision can provide context for the energy changes.
Thus, the correct answer is:
(d) speed and location.

To effectively demonstrate the energy changes during and after the collision of the two identical marbles, focusing on speed and shape would be beneficial. Speed is a direct indicator of kinetic energy (which is proportional to the square of the speed), thus measuring the speed before and after the collision shows how energy is transferred or transformed. The shape, while it may remain the same in a collision between two identical marbles, could theoretically change if they’re deformed or lose energy in the impact, affecting their overall behavior and energy distribution.
Moreover, experiments with colliding objects reveal exciting nuances about energy conservation and transfer. The outcomes can be applied in real-world scenarios, such as understanding vehicle crashes or sports dynamics, where the collision of objects is prevalent. Analyzing the interplay between momentum and energy encourages curiosity about physics and everyday interactions, making it essential to grasp these concepts!
