Question 1

What is motion?

Accepted Answer

Motion is when something is moving from one place to another. It can be as simple as a car driving down the street or as complex as the Earth moving around the Sun.

Question 2

Why do things move?

Accepted Answer

Things move because a force is applied to them. A force can be a push or a pull, like when you kick a ball or pull a toy across the floor.

Question 3

What is gravity?

Accepted Answer

Gravity is the force that pulls things towards each other. It's why we stay on the ground and why things fall when you drop them.

Question 4

What keeps you from floating away from the Earth?

Accepted Answer

Gravity keeps you from floating away! It pulls you and everything else towards the center of the Earth.

Question 5

What is friction?

Accepted Answer

Friction is a force that happens when two things rub against each other. It can slow things down or stop them from moving.

Question 6

Why do bikes have brakes?

Accepted Answer

Bikes have brakes to create friction. When you squeeze the brakes, they press against the wheels and slow you down.

Question 7

How does a car stop?

Accepted Answer

A car stops because the brakes use friction to slow down the wheels. When the wheels slow down, the whole car slows down and stops.

Question 8

What makes a ball fall down when you drop it?

Accepted Answer

The ball falls down because of gravity. Gravity pulls the ball towards the Earth, making it fall.

Question 9

Why do you slip on ice?

Accepted Answer

You slip on ice because it has very low friction. Without enough friction, it's hard for your shoes to grip the ice, making it easy to slip.

Question 10

How do airplanes stay up in the sky?

Accepted Answer

Airplanes stay up because their wings are shaped to lift them into the air. The engines move them forward, and the shape of the wings helps lift them up against gravity.

Question 11

What makes a swing go back and forth?

Accepted Answer

A swing goes back and forth because of the push and pull of gravity and the way you move your body. When you pump your legs, you add more energy and keep the swing moving.

Question 12

How does a frisbee fly?

Accepted Answer

A frisbee flies because of the way you throw it and its shape. The spinning makes it stable in the air, and the curved edges help lift it as it moves forward.

Question 13

Why does a ball roll down a hill?

Accepted Answer

A ball rolls down a hill because of gravity. Gravity pulls it down the slope, and because it's round, it rolls instead of sliding.

Question 14

How does a boat float?

Accepted Answer

A boat floats because it's shaped to push water out of the way, keeping it above the water. Even though a boat is heavy, it displaces enough water to keep floating.

Question 15

Why do some things sink in water?

Accepted Answer

Things sink in water because they're heavier than the amount of water they push away. If something pushes away more water than it weighs, it will float.

Question 16

How do you throw a baseball so it curves?

Accepted Answer

You can throw a baseball to curve by spinning it. The spin changes the air pressure around the ball, making it move in a curve path.

Question 17

Why can't you see the wind?

Accepted Answer

You can't see the wind because it's just moving air, which is invisible. But you can see it moving things like leaves or flags.

Question 18

How do magnets work?

Accepted Answer

Magnets work by attracting certain metals with an invisible force called magnetism. They have a north and a south pole, and opposite poles attract each other while the same poles repel.

Question 19

Why does your hair stand up when you rub a balloon on it?

Accepted Answer

Your hair stands up because of static electricity. When you rub the balloon on your hair, it transfers tiny electric charges that make your hair repel each other and stick to the balloon.

Question 20

What makes a paper airplane fly?

Accepted Answer

A paper airplane flies because you throw it, giving it energy. Its shape helps it glide through the air, and if you fold it right, it can stay up longer and go farther.
