Kinetic Energy and Potential Energy

Front

Landslide Noun

---

[land-slide]

Back

Landslide

---

The sudden and rapid movement of rock, soil, and debris down a sloped surface like a hill or mountain.

---

Example: The image shows how a landslide moves rock and soil down a slope, highlighting key parts like tension cracks and debris pile.

Front

Energy Noun

---

[en-er-jee]

Back

Energy

---

The capacity or ability to do work, which can cause changes in the motion or state of matter.

---

Example: A battery provides energy to light up a bulb, showing energy transfer in a circuit.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

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

---

Example: A cyclist gains kinetic energy as they speed down a hill.

Front

Speed Noun

---

[speed]

Back

Speed

---

The rate at which an object covers a certain distance over a specific period of time, regardless of direction.

---

Example: A ball released from a spring moves quickly, showing speed as it travels a distance.

Front

Mass Noun

---

[mass]

Back

Mass

---

The measure of the amount of matter or substance that is contained within a physical object.

---

Example: A balance scale shows a feather and a rock, illustrating that the rock has more mass.

Front

Potential Energy Noun

---

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

Back

Potential Energy

---

The stored energy an object has due to its position or shape, ready to be converted into another form.

---

Example: A person pushing a ball up a hill shows potential energy due to the ball's position.

Front

Gravitational Potential Energy Noun

---

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

Back

Gravitational Potential Energy

---

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

---

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

Front

Elastic Potential Energy Noun

---

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

Back

Elastic Potential Energy

---

The potential energy stored in an object when it is stretched or compressed, like in a spring or rubber band.

---

Example: Stretching a slingshot's rubber band stores elastic potential energy.

Front

Prosthetics Noun

---

[pros-thet-iks]

Back

Prosthetics

---

The design, creation, and use of artificial devices, known as prostheses, intended to replace a missing body part.

---

Example: This image shows a prosthetic leg with labeled parts, explaining how artificial limbs replace missing body parts.

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 block demonstrates force as a push that can change the object's motion.
