Newton's Laws and Momentum

Zoe and Aiden are having a friendly debate about physics. Zoe says speed and velocity are the same, but Aiden disagrees. Which of the following explains the difference between speed and velocity?

• One has motion, and the other does not.

• One has direction, and the other does not.

• One involves time, and the other does not.

• One involves acceleration, and the other does not.

Imagine Aiden is trying to push a giant snowball uphill. As the snowball gets bigger and heavier, what happens to its ability to speed up? Does it experience a DECREASE in ______________?

• friction

• acceleration

• force

• gravity

Imagine Anika and Benjamin are taking turns on a swing. Anika finds it much easier to push Benjamin than the other way around. Why is it easier for Anika to push Benjamin on the swing?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• None of them

Lily and Michael are having a friendly competition to see who can push harder against a wall. As they both push with all their might, they feel the wall pushing back on them. Which of Newton's laws is at play here?

• Newton's
  1st
  Law of Motion

• Newton's
  2nd
  Law of Motion

• Newton's
  3rd
  Law of Motion

Imagine Kai and Charlotte are playing tug-of-war. What is the term for any push or pull they exert on the rope?

• force

• velocity

• inertia

• momentum

Imagine Arjun and Anika are on a space adventure, launching their rocket into the cosmos! As the rocket zooms upwards, the exhaust blasts out in the opposite direction. Which of Newton's laws is at play here?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• None of them

Imagine you're on a thrilling ride with Zoe and Benjamin, and suddenly the car stops, but you all keep moving forward! Which of Newton's laws is at play here?

During a friendly science competition, Arjun and Aria each drop a piece of paper from the same height. Arjun crumples his paper into a ball, while Aria lets hers fall flat. To their surprise, Arjun's crumpled paper hits the ground first! Why does this happen?

• the acceleration of gravity is greater on the crumpled paper.

• there is more air resistance against the flat paper.

• the crumpled paper is more massive

• the crumpled paper is less massive.

Benjamin and Ava are in a friendly competition to see who can calculate the acceleration of a 50 kg object faster! If they push it with a force of 500 newtons, who will be the first to shout out the correct acceleration using F=m x a?

• 100 m/s²

• 25,000 m/s²

• 10 m/s²

• 25 m/s²

Imagine Harper and Benjamin are on a mission to send a rocket into space. 🚀 When the rocket's power runs out, it will keep floating and moving in space forever (unless an unbalanced force, like a meteor, decides to crash the party). Which of Newton's laws explains this cosmic journey?

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• None of them
