Question
What happens to the energy stores of an object when it is projected upwards?
Answer
When an object is projected upwards, its kinetic energy decreases as it rises, while its gravitational potential energy increases. This is because the object is doing work against the gravitational force, converting kinetic energy into gravitational potential energy.
Explanation
This question tests the understanding of energy transformations in a physical system, specifically how energy is redistributed between kinetic and gravitational potential energy when an object moves against gravity.
Common mistake
Misunderstanding Energy Changes
Students often think that the energy store remains constant when an object is projected upwards.
Emphasize that as an object is projected upwards, kinetic energy is converted to gravitational potential energy, leading to a change in energy stores.
