Final answer:
The increase in potential energy caused by lifting an object can be calculated by multiplying its weight by its change in height.
Step-by-step explanation:
The statement is true. When an object is lifted to a higher height, it gains potential energy. The increase in potential energy can be calculated by multiplying the object's weight, which is equal to its mass multiplied by the acceleration due to gravity, with the change in height. This can be expressed as:
Change in potential energy = weight x change in height
For example, if an object with a mass of 10 kg is lifted 5 meters higher, and the acceleration due to gravity is 9.8 m/s², the change in potential energy would be:
Change in potential energy = 10 kg x 9.8 m/s² x 5 m = 490 J
Therefore, lifting an object increases its potential energy.
