Energy

Front

Energy Noun

---

[en-er-jee]

Back

Energy

---

The ability to cause change or do work, existing in many different forms such as light, sound, and electricity.

---

Example: A battery powers a light bulb, showing energy flow in a circuit.

Front

Motion Noun

---

[moh-shun]

Back

Motion

---

The action or process of an object changing its position over time relative to a specific reference point.

---

Example: A basketball's path shows motion as it changes position over time.

Front

Force Noun

---

[fors]

Back

Force

---

A push or a pull exerted on an object that can cause it to change its motion, direction, or shape.

---

Example: A person pushing a box shows how force can move an object.

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The form of energy that an object possesses because of its motion, which is dependent on its mass and speed.

---

Example: A ball rolling down a slope demonstrates kinetic energy as it moves due to its speed and mass.

Front

Potential Energy Noun

---

[po-ten-shul en-er-jee]

Back

Potential Energy

---

The stored energy an object has due to its position, shape, or chemical composition, ready to be converted.

---

Example: A rock held at the top of a hill has potential energy due to its position.

Front

Speed Noun

---

[speed]

Back

Speed

---

The rate at which an object covers distance over a period of time, which is a factor affecting kinetic energy.

---

Example: A car moving along a road shows speed as the distance it covers over time.

Front

Mass Noun

---

[mas]

Back

Mass

---

The measure of the amount of matter contained within a physical body, which is a key factor in kinetic energy.

---

Example: A balance scale shows a feather and a rock, illustrating how mass affects weight.

Front

Gravitational Potential Energy Noun

---

[grav-i-tey-shun-ul po-ten-shul en-er-jee]

Back

Gravitational Potential Energy

---

The potential energy an object possesses because of its vertical position or height within a gravitational field.

---

Example: A truck on a hill has gravitational potential energy due to its height above the ground.

Front

Elastic Potential Energy Noun

---

[ih-las-tik po-ten-shul en-er-jee]

Back

Elastic Potential Energy

---

The potential energy stored in an object as a result of its deformation, such as being stretched or compressed.

---

Example: Stretching a slingshot stores elastic potential energy in the rubber band.

Front

Energy Transformation Noun

---

[en-er-jee trans-for-mey-shun]

Back

Energy Transformation

---

The process by which energy changes from one form to another, for example from electrical to thermal energy.

---

Example: A battery powers a light bulb, showing electrical energy transforming into light energy.
