Answer

Lifting vertically requires more energy because it must overcome gravitational force, whereas sliding horizontally on a frictionless surface requires no energy input. Explanation 1. Identify Forces in Vertical Lifting Lifting vertically requires overcoming gravitational force. **Work done** is calculated using W = F \cdot d, where F is the force due to gravity (mg) and d is the vertical distance. 2. Identify Forces in Horizontal Sliding On a frictionless surface, no force is needed to slide horizontally, as there is no opposing force like gravity or friction acting against the motion. 3. Compare Energy Requirements Vertically lifting requires energy to overcome gravity, while sliding horizontally on a frictionless surface requires no energy input since no force opposes the motion.

Explanation

1. Identify Forces in Vertical Lifting<br /> Lifting vertically requires overcoming gravitational force. **Work done** is calculated using $W = F \cdot d$, where $F$ is the force due to gravity ($mg$) and $d$ is the vertical distance.<br /><br />2. Identify Forces in Horizontal Sliding<br /> On a frictionless surface, no force is needed to slide horizontally, as there is no opposing force like gravity or friction acting against the motion.<br /><br />3. Compare Energy Requirements<br /> Vertically lifting requires energy to overcome gravity, while sliding horizontally on a frictionless surface requires no energy input since no force opposes the motion.
