Give an equation of motion for the height of a falling object.
Open in App
Solution
An object that is falling on the surface of the earth (with an initial velocity ‘zero’) experiences acceleration due to gravity (g) in a downward direction.
The object reaches the ground from height (h) after the time (t), where its final velocity becomes ‘v’.
From the equation , we get
Hence, the equation of motion for the height (h) of the object,
