## Would a brick or feather fall faster?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.

A feather and brick dropped together.

Air resistance causes the feather to fall more slowly..

## Why do objects hit the ground at the same time?

Originally Answered: why two object with different mass hit the ground at the same time when droppes from the same height ? It is because the acceleration due to gravity is constant for all objects regardless of the mass, neglecting air resistance. … So the acceleration is constant for all objects.

## Does weight affect how fast an object falls?

Both objects fall at the same speed. Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time.

## Why do heavy and light objects fall at the same rate?

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth’s surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

## Why does a heavier object hit the ground first?

In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.

## Is value of G actually constant?

The force of attraction between any two unit masses separated by a unit distance is called universal gravitational constant denoted by G measured in Nm2/kg2. It is an empirical physical constant used in gravitational physics. … The value of the gravitational constant is the same throughout the universe.

## What would fall first a feather or a rock?

If you drop a feather and a rock at the same time, you know the rock will hit the ground first and the feather will fall much slower.

## Who invented gravity?

Sir Isaac NewtonSir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.

## Who dropped balls off the Leaning Tower of Pisa?

Galileo Galilei: Four hundred years ago–or so the story goes–Galileo Galilei started dropping things off the Leaning Tower of Pisa: Cannon balls, musket balls, gold, silver and wood. He might have expected the heavier objects to fall faster. Not so.

## What will fall first watermelon or egg?

Since the egg is lighter, the gravitational force is less. … So since the watermelon has a greater gravitational force AND lower acceleration – the two effects cancel each other out perfectly, allowing it to hit the ground the same time as the egg.

## Why does a feather fall slower than a brick?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls.

## What is the fastest anything can fall to earth?

Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph) for a human skydiver.

## Why does a heavy object not fall faster?

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass. … If the car drives faster, the air resistance force gets larger.

## Why did Aristotle believe that heavier objects fall faster than lighter objects?

But there is something impressively consistent, universal, and inexorable about the way things fall. Stand up now and simultaneously drop a coin and a bit of paper side by side. The paper takes much longer to hit the ground. That’s why Aristotle wrote that heavy objects fell more rapidly.

## How far do you fall in 3 seconds?

S=displacement ,u=initial velocity, t=time, a=acceleration . Here acceleration is acceleration due to gravity g,g=9.8 m/s^2 and initial velocity is zero. S=1/2*9.8*9=44.1 meter. You will fall 44.1 meters in 3seconds.

## Do heavier objects roll down a ramp faster?

Start your bowling ball and your golf ball at the same spot on the ramp and let go at the same time. If our intuitive sense of this situation is right, and heavier things fall faster than lighter ones, then they should also roll faster. Putting them on a ramp only slows things down so it’s easier to watch.

## Do heavier objects go downhill faster?

When objects slide down a slope, the downward force acting on them to produce acceleration is (mg cos@ – friction) and = ma. So acceleration, a = g cos@ – friction/mass. The heavier object will have a higher acceleration and so arrive faster. … The heavier object will have a higher acceleration and so arrive faster.

## How does mass affect speed?

2 Answers. Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.
