Let's solve the "Force and Motion" worksheet step by step using the provided word bank:
Word Bank:
Force, work, friction, rest, gravity, motion, shape, spring scale, lubricants
---
1. A force that resists motion when objects touch is called friction.
✔ *Friction* opposes motion between surfaces in contact.
---
2. A force that pulls two objects towards each other is called gravity.
✔ *Gravity* is the attractive force between masses (e.g., Earth pulling objects down).
---
3. Any push or pull is called force.
✔ This is the definition of a *force*.
---
4. A change in position is called motion.
✔ *Motion* refers to an object changing its position over time.
---
5. A tool used to measure the force is called spring scale.
✔ A *spring scale* measures force (like weight) by stretching a spring.
---
6. When an object is not in motion it is called rest.
✔ An object at *rest* has no motion (zero velocity).
---
7. The unit of force is the newton.
✔ The *newton (N)* is the SI unit of force (named after Isaac Newton).
---
8. A force moving an object at a distance is called work.
✔ *Work* is done when a force causes displacement: Work = Force × Distance.
---
9. On squeezing a gum tube, its shape changes.
✔ Squeezing deforms the tube — this is a change in *shape*.
---
10. Lubricants are used to reduce friction.
✔ *Lubricants* like oil reduce friction between moving parts.
---
✔ Final Answers:
1. friction
2. gravity
3. force
4. motion
5. spring scale
6. rest
7. newton
8. work
9. shape
10. lubricants
All answers come directly from the word bank and match the definitions perfectly!
