Observe the 2 bottles of paint with a notecard in between. As we attempt to remove the card without disturbing either bottle, which of Newton's Laws does this represent?

Observe las 2 botellas de pintura con una tarjeta de notas en el medio. Mientras intentamos quitar la tarjeta sin molestar ninguna botella, ¿cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Inertia causes the bottles of paint to stay in place. No force has acted upon them, so there is not motion.

Watch as Blake pushes the 2 cars of different masses with about the same force. Observe what happens. Which of Newton's Laws does this represent?

Observa cómo Blake empuja los 2 coches de diferentes masas con aproximadamente la misma fuerza. Observa lo que pasa. ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Newton's 2nd Law is the relationship between force, mass and acceleration. The car with less mass travels further when pushed with the same force as the car with more mass.

Watch as I send the car down the track. What happens as I increase the force that I am using? Which of Newton's Laws does this represent?

Mira como mando el coche por la pista. ¿Qué sucede cuando aumento la fuerza que estoy usando? ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

The more force I apply, the greater the acceleration.

Watch as Blake begins to run. What happens to the sheets of paper under his feet? Why? Which of Newton's Laws does this represent? Mira como Blake comienza a correr. ¿Qué pasa con las hojas de papel bajo sus pies? ¿Por qué? ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

The action is Blake pushing off into the ground/paper to run. The reaction is the papper accelerating out the opposite direction!

Observe the motion of the washer as I quickly pull the card out from under it. What happened to the washer? Why? Which of Newton's Laws does this represent? Observe el movimiento de la moneda mientras saco rápidamente la tarjeta de debajo. ¿Qué pasó con la moneda? ¿Por qué? ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Because the washer is at rest, it wants to stay at rest. no force is applied directly to the washer, so becuase of inertia, it stays on the table.

Observe as the first ball hits the first ball in the line on the pendulum. What happens to each ball in succession? Which of Newto's Laws does this represent? Observar cómo la primera bola golpea la primera bola en la línea del péndulo. ¿Qué pasa con cada bola en sucesión? ¿Cuál de las leyes de Newto representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

As the first ball hits the second ball, the force is passed as momentum to each ball after, thus proving that when two objects collide, the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision. This is seen through the movement of the last ball in the line.

Watch the first marble as it collides with the second marble . Which of Newton's Laws does this represent? Observar cómo choca la primera canica con la segunda canica. ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

As the marble accelerates down the ramp, it's net force causes the marble at the bottom to accelerate.

Watch as I propel the washers across the desk. Observe what happens as I use different amounts of force. Observa cómo empujo las monedas por el escritorio. Observe lo que sucede cuando uso diferentes cantidades de fuerza.

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

The more force I used, the greater the acceleration of the washers, and the further they traveld.

A soccer ball is sitting in the middle of a field. The ball will remain at rest until an outside force like a players foot or the wind acts upon it. Which of Newton's laws is represented by this?

• 1st

• 2nd

• 3rd

Think about pushing a shopping cart and a car. If you apply the same amount of force to both, the shopping cart will travel fast, but the car will hardly move. To move the car yo would need a larger force. Which of Newton's laws is being represented?

• 1st

• 2nd

• 3rd
