Simple Machines
Law of Conservation of Energy
Potential vs. Kinetic
Is it kinetic or potential?
Energy Transfer
100

The purpose of all simple machines is to make work easier by reducing this

What is the amount of effort and force used (or just effort/force)?

100

The fundamental law of stating energy cannot be created or destroyed, only changed in form

What is the law of conservation of energy?

100

This type of energy is based on an object's motion.

What is kinetic energy?

100

This type of kinetic energy is caused by vibrating molecules and affects temperature.

What is thermal energy?

100

The two energy forms released when a cow eats grass.

What are Thermal and Kinetic energy?

200

This is a simple machine that is a rigid bar or plank with a pivot point known as the fulcrum

What is a lever?

200

This property of energy stays the same even as energy is converted into different forms.

What is the amount of energy?

200

This is the kind of energy a ball has when it reaches the top of a hill and is momentarily stopped due to its position.

What is potential energy?

200

Energy stored in a stretched rubber band or a pulled back bow.

What is Elastic Energy?

200

In a radio powered by batteries, chemical energy immediately changes to this, before becoming sound.

What is Electrical Energy?

300

An inclined plane that is movable, like an axe, knife, or doorstop

What is a wedge?

300

This is the term for the movement of energy between different stages.

What is an energy transfer?

300

When a moving object slows down and stops, its kinetic energy is transferred into this other type of energy, relative to its new position.

What is potential energy?

300

The type of potential energy that a skydiver possesses due to their height above the Earth's surface.

What is gravitational energy?

300

The four forms of energy created by turning on a light bulb, starting from the initial source (batteries or power grid).

What are Chemical, Electrical, Light, and Sound energy?

400

This class of lever has the fulcrum in the middle, between the load and the effort (e.g., a seesaw)

What is a first class lever?

400

This is what the Law of Conservation of Energy says can happen to energy, but it can never be destroyed.

What is change forms/transferred?

400

This is the energy conversion that happens when a ball rolls down a hill.

What is the conversion of potential energy to kinetic energy?

400

Energy stored in the nucleus of radioactive atoms.

What is nuclear energy?

400

The energy chain that starts with Electrical Energy and results in Light, Sound, and Thermal energy.

What is a TV Change (or TV being turned on)?

500

A wheelbarrow is an example of this class of lever because the load is in the middle and the fulcrum is to one side

What is a second class lever?

500

This is the action that allows us to release stored chemical energy from our bodies and convert it to mechanical energy.

What is movement?

500

The two factors that influence the amount of potential energy an object possesses.

What are force applied and the distance?

500

The transfer of energy via molecules bumping into each other to transmit waves.

What is sound energy?

500

The complete energy conversion chain that occurs in a TV when you turn it on.

What is Electrical to Sound to Light to Thermal energy?
