Back to the 2nd Law

A shot put has a much greater mass than a discus. How does Newton's second law explain why a discus can be thrown twice as far as a shot put?

A discus can be thrown father than a shotput ball because it's alot lighter than a shotput ball, and takes alot less force to throw.

Evan L said...

Discus has less mass so it wieghs less so it can go further if thrown, because they are easier to throw, then a shotput.

Griffin M. said...

I think the discus has less mass and it is lighter.

Ben S. said...

Well, the discus can be thrown farther with the same acceleration because F=ma, which means you need more force to throw the shot put the same distance as the discus.

It can be thrown because it is lighter.

I think it is because discus gets more acceleration. Also it is a lot lighter than a shot put ball, which makes it easier to throw.

what gary said .xXOWENXx.

Even if you do throw it with the same force, because the shotput ball has more mass it dons;t accelerate as much,

The discus can be thrown twice as far as the shot put because you need more force to throw the shot put than the discus.

I have no idea..

Brendan S said...

I think it has a much greater mass because it get's more acceleration. It is also a lot lighter in weight which makes it more easy to throw and will go further.

Griffin M. said...

So therefore it can be thrown farther with more acceleration

Mya N said...

Discus has less mass so it weighs less so it can fly further when it is thrown, because they are easier to throw then a shot put.

Leslie K said...

*doesn't*

Tyler J said...

because its lighter and more arrow dynamic and the shot put is extremely heavy and hard to throw

Jacob G said...

The less the mass, the farther it goes.

Since the discuss has a lighter mass then it goes further.

Amber R said...

the sot put is heavier so gravity acts more on it.

Amelia A said...

The Discus has less weight and can be thrown further like a Frisbee, unlike the shot put where you throw it up in the air. And gravity can pull the shot put down to the ground faster.

Julia M said...

The discus has less weight and can be thrown further because there's less gravity pulling on it, and a shot put is heavier so it requires more force to go further because there's more gravity acting on it.

The discus is lighter so It can be thrown farther! :D :p :3

The discus is lighter therefore it has less resistance and it will go farther.

Noah L. I think the discus has less mass and it is lighter.

because it takes greater force to move something with more mass

Patrick H said...

Discus has less mass so it weighs less so it can fly further when it is thrown, because they are easier to throw then a shot put.

The less the mass, the farther it goes.

The less the mass, the faster it goes.

discus has less weight,so it is thrown and flies farther then then a shot put

Jacob T said...

The Less mass the farther it goes

Discus has less weight so it will go farther.

A discus is not a compacted mass and the shotput is so the discus will travel farther

Adrian K said...

The discus has less mass so it will go farther than the shot put.

Jennifer C said...

Easy. The shotput is heavier, and has a lot more mas so it takes a lot more strength to throw, and it will go less far than a discus would. Go hunt an elephant in your backyard. Now pick it up and throw it. Not so easy, is it? Didn't think so.

Jacob L said...

The discus is not a compacted mass so it would travel farther

McKayla. M said...

The discus has less mass so it will travel farther.

Molly B said...

less mass the further it goes!

lindseyb said...

because it has less mass so it can be thrown farther

AutumnP said...

The discus isn't a compacted mass so it would travel farther.

Abbie N said...

The discuss does not have as much weight or mass so it is more easily thrown.

Kanani L. said...

The discus has a smaller mass then the shot put. So the discus could been thrown farther!!!!1

Hannah Corbet can throw it 50 ft

Uhhh, I can thrown it 34 ft
