Changes in Force and Motion

Front

Force Noun

---

[forss]

Back

Force

---

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

---

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

Front

Motion Noun

---

[moh-shun]

Back

Motion

---

The change in an object's position over time when compared to a fixed reference point.

---

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

Front

Reference Frame Noun

---

[ref-er-uhns fraym]

Back

Reference Frame

---

A system using coordinates or background objects to describe the position or movement of something in space.

---

Example: A cyclist's movement is shown using arrows to indicate changes in position relative to the ground.

Front

Reference Point Noun

---

[ref-er-uhns point]

Back

Reference Point

---

A stationary location or object used to determine the position or motion of another object.

---

Example: A number line shows Kosma's house as a reference point to determine positions of school and shop.

Front

Position Noun

---

[puh-zish-uhn]

Back

Position

---

The specific place or location that an object occupies within a given coordinate system or reference frame.

---

Example: A basketball's path shows its position at different points as it moves towards the hoop.

Front

Potential Energy Noun

---

[poh-ten-shuhl en-er-jee]

Back

Potential Energy

---

The stored energy an object possesses due to its position, state, or chemical composition.

---

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

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The energy an object has because of its motion, which increases with its mass and speed.

---

Example: A moving ball in Newton's cradle shows kinetic energy through motion.

Front

Speed Noun

---

[speed]

Back

Speed

---

The rate at which an object covers distance over a certain period, calculated as distance divided by time.

---

Example: A car moving along a track illustrates speed as distance divided by time.

Front

Velocity Noun

---

[vuh-los-i-tee]

Back

Velocity

---

A measure of an object's rate of motion that specifies both its speed and its direction.

---

Example: Cars moving in different directions with arrows show velocity as speed with direction.

Front

Acceleration Noun

---

[ak-sel-uh-rey-shuhn]

Back

Acceleration

---

The rate at which an object's velocity changes over time, including speeding up, slowing down, or changing direction.

---

Example: A spring pushes a ball, showing acceleration as the ball speeds up and moves forward.
