Let’s Get Rolling! Physics for Kids

The video follows a teacher and Squeaks as they collect rocks and face the challenge of moving a heavy box. They explore the use of simple machines, specifically wheels and axles, to solve the problem. By placing the box in a wagon, they demonstrate how wheels and axles reduce the force needed to move heavy objects, making it easier to transport them over long distances.

What problem did Squeaks and the narrator face with their rock collection?

• They lost the box.

• The box was too heavy to carry.

• The box was too light.

• The rocks were too small.

Which simple machine did the narrator decide to use to move the heavy box?

• Lever

• Pulley

• Inclined Plane

• Wheel and Axle

What is the main function of a wheel and axle?

• To change the color of an object

• To increase the weight of an object

• To make an object spin faster

• To reduce the force needed to move an object

Which of the following is NOT an example of a wheel and axle?

• Car

• Pulley

• Roller skates

• Bicycle

Why are wheels and axles used in many transportation devices?

• They are only used for decoration.

• They require more force to move objects.

• They make objects heavier.

• They make it easier to move objects over long distances.
