Question

When a ball is thrown upward, its total energy:

• A. increases
• B. decreases
• C. remains same
• D. none of these

Answer 1

The correct option is C

remains same

Explanation for correct answer:

1. When a ball is thrown upward, kinetic energy keeps on decreasing whereas potential energy keeps on increasing but the total energy of the ball will remain the same.
2. The velocity is zero when the ball reaches maximum height. Hence no kinetic energy but only potential energy exist.

Thus, when a ball is thrown upward, its total energy remains same. Hence, option ‘c’ is correct.
