Third Law in Action

How does Newton's Third Law explain the direction a boat crew must move the oars in order to move the boat forward?

Because when they push one way they go the other way

Newton 3rd law states that for every action there is equal and opposite reaction. So the people rowing the boat must row backwards to move forwards.

Because when they push one way they go the other way

When the boat crew rows, the water goes in the same direction, sending the boat in the opposite direction

Evan L said...

Because if they move the oars one direction, it moves the water forward so it makes the boat go forward.

Griffin M. said...

They need to move both sides at the same speed to make it go straight.

You copied Rylan please post your own

Because when you are pushing the water back, the boat is going forward.

For every action there is equal and opposite reaction. The people in the boat have to row backwards.

when you row you are pushing the water behind lunging the boat foreword.kinda like a modle rocket when the fulel goes out it goes up

Katie N. said...

By pushing against the water you go farther.

As Leslie had said, Newton's 3rd law does clearly state that for every reaction there is an equal and opposite reaction. This means the crew on the boat needs to row backward in order to move forward. The oars going backward accelerate the boat forward.

The crew team uses Newton's third law of motion to move its boat. When an oar is put into the water, the water exerts an equal force on both sides of the oars, the surface of the flat side of the oars pushes against the water. The water pushes back on the oars with an equal and opposite force. The boat moves in the opposite direction of the oars with a force that is equal to that of the oars as they push against the water. The boat moves because the forces against it are unbalanced.

Magic!

That the rowers have to push the opposite way to move forward.

at least i did something

The oars push against the water to go forward or backwards.

The oars*

Newton's third law explains the direction of the boat because when the crw pushed one way they go the other way.

They like push one way to go the other.

they push force one way witch comes back to them and puts the force on them

The oars make acceleration, and push the boat forward with there force, and momentum.

Jacob G said...

Newton's 3rd Law refers to with every action it has a equal and opposite reaction so when the oar pushes the water back, the boat goes forward.

Sadie F. said...

When pushed one way the boat goes the other.

Julia M said...

Newton's third law says that with every action there is an opposite and equal reaction. To go forward, the people in the boat need to row backwards.

Using Newtons 3rd Law: Force Pushes the boat forward thus Using Newtons 3rd Law!

Adrian K said...

Because its pushing and pulling.

Newtons third law says for every action there is an equal and opposite reaction. The oars are pushing back the water which is pushing the boat forward.

The third law says that every action there is an opposite abd equal reaction. To go forward the people in the boat have to row backwards.

McKayla.M said...

Newtons third law you need to go forward but you have to row backwards to move

lindseyb said...

because they put the oar in the water and push back and then when they push back they move forward.

Molly B said...

When the boat crew rows, the water goes in the same direction, sending the boat in the opposite direction

Abbie N said...

Newtons third law applies to this because you have to row backwards to move forward.
