NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
When an object is released from a height h above the ground, what is the relationship between its speed just before hitting the ground and the height from which it was released?
A
v = √(2gh)
B
v = gh
C
v = 2gh
D
v = √gh
Correct Answer
Option A
Detailed Explanation
The speed of an object just before hitting the ground is given by the kinematic relation v² = 2gh, which simplifies to v = √(2gh). This is derived from the conversion of gravitational potential energy to kinetic energy.
