Text, Questions & Answers

Dave and Mia were playing tag in the park when Dave tripped over a stone and fell. 'Why did I fall down?' Dave wondered aloud. Suddenly, a superhero named FlashForce appeared. 'That's because of gravity,' he explained. 'It's a force that pulls everything towards the Earth.' Later, Dave and Mia found an old box they wanted to move. Despite their best efforts, the box wouldn't budge. FlashForce explained that it was because of another force called friction, which slows down motion. After a day of play and unexpected lessons in physics, Dave and Mia realized that forces are at work all around them.

Question 1

Why did Dave fall down?

Because of gravity

Explanation. Gravity is a force that pulls everything towards the Earth. Dave fell down because gravity pulled him towards the Earth after he tripped on a stone.

Because he is clumsy

Because of the wind

Because Mia pushed him

Because he was running too fast

Question 2

What is gravity?

A type of friction

A force that pushes everything away from the Earth

A force that pulls everything towards the Earth

Explanation. Gravity is a force that pulls everything towards the Earth. It is what makes things fall to the ground when they are dropped.

A type of energy

A superhero

Question 3

Why couldn't Dave and Mia move the box?

Because they were too weak

Because the box was glued to the ground

Because of gravity

Because of friction

Explanation. Friction is a force that opposes motion. It was the friction between the box and the ground that made it difficult for Dave and Mia to move the box.

Because the box was too big

Question 4

What did Dave and Mia learn from FlashForce?

How to play tag

How to fly

How to move a box

The concepts of gravity and friction

Explanation. FlashForce explained to Dave and Mia the concepts of gravity, which pulls everything towards the Earth, and friction, which slows down motion.
