Science and Hockey

You hit a hockey puck and it slides across the ice at nearly a constant speed. Is a force keeping it in motion? Explain.

It is slipping across the ice.

Katie N. said...

Sooo I guess that counts as a force.

Anonymous said...

Yes theres a force agenst it.

Rylan N said...

No there is just less friction on the ice and the force is from the hockey stick

Griffin M. said...

Yes it is sliding across the ice and the ice is smooth so there isn't much friction.

Casey K said...

There is no force its the ice slipping it around.

Leslie K said...

Yes, The force is the ice, it keeps the puck moving at the speed the hockey stick gives it.

Jack D said...

It is still going until an outside force acts upon it and stops it or it will slow down and stop.

Mercedes C. said...

Yes,Because puke is sliding across the ice.

Evan L said...

Yes because it stays in motion so a force must be acting on it.

Puck*

If it's staying in motion, and friction isn't stopping it, than I think a force is acting upon it.

Lauren B. said...

The ice has less friction therefore making it able to keep the puck at a nearly constant speed. The force is not much friction, and the ice.

Brendan S said...

Yes, the force is the ice. It is keeping the puck in movement.

Samantha L said...

Yes, when sliding across the ice, the ice is smooth so there isn't much friction.

Mya N said...

Yes the force that started it but it doesn't keep it moving.

Lauren B. said...

It is INTERIA with ACCELERATION!

Leslie K said...

Also inertia and acceleration are acting on it.

King of Everything except for the MINIONS said...

Yes it is staying in motion because when you hit the puck it slides across the ice and makes it so when it hits its target it slows down or stops completely

Casey K said...

Because there is less friction in the ice.

Ben S. said...

Yes, the push from the hockey stick starts the force, but the ice (which has no force) keeps it moving via inertia

Yes, sliding force keeps it in motion.

It think it is because like sliding force is keeping it that way.

Sadie F. said...

Yes, the force is the hockey stick pushing the puck.

Yes, because sliding keeps force in motion.

Ella T. said...

I think it has something to do with inertia and acceleration...

Jacob G said...

Yes because the stick hits the puck and the ice is slippery so it stays in motion.

Julia M said...

Yes, inertia is keeping the puck moving.

Kaylee H. said...

Yes, sliding force keeps it in motion.

stuff and more thinysssssssssssssssssssssssssssssssssssssssssss

jacob t said...

Yes it is sliding across the ice and the ice is smooth so there isn't much friction.

there is a force pushing the hockey puck across the ice it is being pushed.

Well Mr. Ruby, that is a very interesting question. A question I don't know the answer to. (I'll reply after the followup.)

Yes and explanations and reasons.

yes

Sophia S:) said...

Its INERTIA, NO FORCE AT ALL!! AHA SCIENCE!!

Jennifer C said...

When the puck is sliding on the ice, there's no force being exerted on it. Inertia keeps it going.

Cassie :D said...

No. A inertia is the force acting on the puck. :D

Gavin MacDonald said...

Yes, Sliding friction is making this puck move across the ice because the human that hit the puck gave it a push to go.

Matthew G said...

NO FORCE AAAAAAA

McKayla. M said...

Yes the force of the puck is pushing it across the ice.

AutumnP said...

Yes, The force of the stick is pushing the puck.

Elsa L said...

Sliding friction is acting on the hockey puck because you hit it with a hockey stick.

Mackenzie E said...

Yes, The force is the ice, it keeps the puck moving at the speed the hockey stick gives it.

Maria said...

Yes for a while because it has frictions what then it comes to a stop.

Molly B said...

Yes, The force of the stick pushed the puck!.

Devon Sargent said...

Yes because there a person behind consent, but only when needed.

Anonymous said...

no because he only touched it once.

Kanani L. said...

Yes, the force is keeping it in motion, but it isn't a consist force. The interia keeps the puck moving

BillyM said...

Yes, the force is the ice and the ice keeps the puck moving

DavidM said...

yes it was force that pushes it along

Ashleigh L said...

More the force on the push to make th puck go is further it goes.

Abbie N said...

There is no force acting upon it it's inertia.
