Final answer:
Slips are true to occur due to loss of balance or when one's foot encounters an obstruction, disrupting traction and potentially causing a fall.
Step-by-step explanation:
The statement 'Slips occur due to loss of balance or contacting an object or obstruction' is True. Slips typically occur when there is not enough traction or friction between the footwear and the walking surface, leading to a loss of balance. Additionally, slips can happen when a foot unexpectedly encounters an object or obstruction, leading to a sudden change in motion and potential loss of balance.
