Explanation:
When a coin and a feather are dropped simultaneously from the same height, the coin strikes the ground first.
→ The weight of the coin is more compared to the weight of the feather.
→ The substance with more weight experiences more air resistance(frictional force) than smaller objects like feathers.
→ The coin falls much longer before it gathers enough speed so that air resistance will balance the gravitational force on it. And the feather acquire no more speed, but just moves slowly downwards.
→ The force exerted by gravity on the stone will be greater than the force exerted on the feather.
Therefore:-
When a coin and a feather are dropped simultaneously from the same height, the coin strikes the ground first due to the Frictional Force is less in the case of the coin.
Answer:
Explanation:
Both coin and feather will reach the ground at same height because in vacuum the motion of a body does not depend on its mass since there is no gravity.
Hence any free falling body in vacuum will reach the ground at same time.

Gravity formula
In the first equation above, g is referred to as the acceleration of gravity.
Its value is 9.8 m/s2 on Earth.
That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location

What is meant by magnetic force?
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ...
The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
