## What hits the ground first feather or brick?

A feather and brick dropped together.

Air resistance causes the feather to fall more slowly.

If a feather and a brick were dropped together in a vacuum—that is, an area from which all air has been removed—they would fall at the same rate, and hit the ground at the same time..

## Will 2 objects fall same speed?

Free Fall Motion Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

## 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 falls faster a watermelon or an 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.

## 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.

## Will 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.

## Do heavier objects fall faster than lighter objects?

Answer 3: In real life, heavier objects sometimes fall faster than light objects, but not because of gravity. Gravity makes all objects increase their speed at the same rate, regardless of how big they are. But if you drop 2 things outside, the air molecules may slow down one thing more than another.

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

Why do heavy and light objects fall at the same speed? … Basically this means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity. This is just the way gravity works – it accelerates everything at exactly the same rate.

## Do heavier objects roll faster?

The force acting on the body that pulls the body down is the force of gravity. We know that for sure. … Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.

## Which object will fall first?

Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first. This is trick question. I remember in physics that everything falls the same.

## Does mass affect speed?

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.

## Why do objects with heavier mass 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. … Air resistance causes the feather to fall more slowly.

## Why does a hammer hit the ground before a feather?

This is because the feather reaches it’s terminal velocity quicker, because its air resistance increases as it falls. … The hammer is much heavier, so it travels faster, before air resistance is large enough to balance its weight.

## Do heavier objects accelerate faster downhill?

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 do you calculate the force of an object hitting the ground?

The first step is to set the equations for gravitational potential energy and work equal to each other and solve for force. W = PE is F × d = m × g × h, so F = (m × g × h) ÷ d. The second and final step is to plug the values from the problem into the equation for force.
