Newtons Laws

Observe what happens to the motion of the penny. Which of Newton's Laws does this represent?

Observe lo que sucede con el movimiento del centavo. ¿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 1st Law of inertia causes the penny to stay in place/drop straight down and enables me to catch it right where my elbow used to be.

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.

Observe the motion of the washer as the notecard is pulled quickly out from under it. Which of Newton's Laws does this represent?

Observar el movimiento de la moneda mientras saca rápidamente el papel de debajo. ¿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 of inertia, the washer will drop down into the cup as the card is pulled away. When the card is moved the object wants to stay at rest, until gravity acts, pulling it straight down.

Watch what happens as Blake releases the balloon. Which of Newton's Laws does this represent?

Mira lo que sucede cuando Blake suelta el globo. ¿Cuál de las leyes de Newton representa esto?

• Newton's 1st Law, interia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

As the air rushes out of the balloon, the balloon is propelled forward. Action = air rushes out Reaction = Balloon shoots forward.

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.

As Blake spins the bucket around, observe the motion of the washers. Which of Newton's Laws does this demonstration represent?

Mientras Blake hace girar el cubo, observe el movimiento de las monedas. ¿Cuál de las leyes de Newton representa esta demostración?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Answer explanation

Inertia causes the washers to press away from the center of the rotation (where the force is coming from) the bucket keeps the washers from flying off into the room.

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.

As I balance a meter stick and a ruler on my fingers, which one is easier to balance? Why? Which of Newton's Laws does this represent?

Mientras balanceo un metro y una regla en mis dedos, ¿cuál es más fácil de equilibrar? ¿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

As the sticks balance on my fingers, they show interia. Also, the meter stick is easier to balance because the more weight on your finger, the greater the force of friction. The Meter stick has more mass and therefore more friction.

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.

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.
