- 1Decreasing the angle decreases the energy absorption due to a shorter impact time.
- 2Deviating from the standard height and angle invalidates the test results because the potential energy must remain constant as per testing standards.✓
- 3Varying the angle does not significantly affect energy absorption but increases the test's sensitivity.
- 4Increasing the angle increases the energy absorption due to a longer impact time.
Correct answer
Deviating from the standard height and angle invalidates the test results because the potential energy must remain constant as per testing standards.
