Gravity is a force that pulls objects towards each other. On Earth, gravity pulls everything towards the ground, which is why things fall down. The bigger an object is, the stronger its gravity. When an object falls, it speeds up because of gravity. We call this acceleration. Understanding gravity helps us predict how things move!
Falling objects are affected by gravity and air resistance. Air resistance is the force of air pushing against a moving object. A feather falls slower than a rock because it has more air resistance. If there was no air, everything would fall at the same speed!
Match the words with their definitions:
| Words | Definitions |
|---|---|
| 1. Gravity | A. The force that opposes motion through the air. |
| 2. Air Resistance | B. The speed at which an object is falling. |
| 3. Acceleration | C. The force that pulls objects towards each other. |
| 4. Weight | D. The rate at which an object speeds up. |
| 5. Terminal Velocity | E. The measure of how strongly gravity pulls on an object. |
Complete the sentences using the words: gravity, faster, air resistance, Earth, weight.
