Vocabulary worksheet for forces, motion, and energy concepts.

Let’s go step by step through each vocabulary term based on the definitions given. We’ll match each definition to the correct science word.

---

1. The location of an object
→ This is called position. In science, we say “position” to mean where something is located.

2. The length of the space between the starting point and ending point
→ That’s distance. Distance measures how far apart two points are.

3. The tilt or course along which something moves, faces, or lies
→ This describes direction. Direction tells us which way something is going or pointing (like north, left, up, etc.).

4. A change in an object’s position over time
→ That’s motion. If something changes its position as time passes, it’s moving — that’s motion.

5. A group of objects from which you can measure a position or motion
→ This is a frame of reference. For example, if you’re sitting in a car, the trees outside seem to move — but really, your frame of reference (the car) is moving.

6. Any push or pull
→ That’s a force. Forces make things start moving, stop moving, or change direction.

7. A force that occurs as objects touch
→ This is a contact force. Like when you push a book across a table — your hand touches the book.

8. When moving objects speed up, slow down, or change direction. How fast they accelerate depends on the force.
→ This describes acceleration. Acceleration isn’t just speeding up — it includes slowing down or turning too.

9. When forces act on each other without changing its motion: “A balanced force always adds up to zero”
→ These are balanced forces. If equal forces push from opposite sides, nothing moves — like tug-of-war with equal teams.

10. Forces that do not cancel each other out and that cause an object to change velocity
→ These are unbalanced forces. They make things speed up, slow down, or turn — because the pushes/pulls aren’t equal.

11. A noncontact force that acts over a distance and pulls objects toward each other
→ That’s gravity. Gravity pulls things together even if they’re not touching — like Earth pulling you down.

12. A force that opposes the motion of one object moving past another
→ That’s friction. Friction slows things down — like when you slide on carpet vs. ice.

9. Balanced forces
10. Unbalanced forces
11. Gravity
12. Friction
