Acceleration due to gravity in vacuum is same irrespective of size and mass of the body

Vedclass · Answer

(A) The equation of motion for an object falling from rest from a height $h$ is given by $h = \frac{1}{2}gt^2$,where $g$ is the acceleration due to gravity and $t$ is the time taken.Solving for $t$,we get $t = \sqrt{\frac{2h}{g}}$.In a vacuum,there is no air resistance,and the acceleration due to gravity $g$ is independent of the mass and size of the falling object.Since both balls are released from the same height $h$ and experience the same acceleration $g$,the time taken $t$ to reach the ground will be the same for both.Therefore,the correct option is $A$.

An iron ball and a wooden ball of the same radius are released from a height $h$ in vacuum. The time taken by both of them to reach the ground is equal based on:

Similar Questions

$A$ person sitting on the ground floor of a building notices through a window of height $1.5 \; m$ that a ball dropped from the roof of the building crosses the window in $0.1 \; s$. What is the velocity (in $m/s$) of the ball when it is at the topmost point of the window? (Take $g = 10 \; m/s^2$)

$A$ person throws balls into the air vertically upward at regular intervals of time of $1 \,s$. The next ball is thrown when the velocity of the ball thrown earlier becomes zero. The height to which the balls rise is (Assume $g = 10 \,m/s^2$) (in $\,m$)

$A$ ball is thrown vertically upwards with a speed of $10 \ m/s$ from the top of a tower $200 \ m$ high and another is thrown vertically downwards with the same speed simultaneously. The time difference between them in reaching the ground (in $s$) is: $(g = 10 \ m/s^2)$

Write the equation of velocity of an object falling freely from height $h$.
