Step-by-step solution for: Third Grade Force And Motion Worksheets
Since I can't view or access images directly, I can't see the specific content of your uploaded image. However, based on the text you've provided, it appears to be a worksheet titled "Forces & Motion" with fill-in-the-blank sentences using vocabulary words like:
- push
- pull
- gravity
- friction
- force
- inertia
- machine
- energy
- balance
- Newton
Let me solve the worksheet for you by filling in each blank with the most appropriate word from the list, and then explain the reasoning behind each answer.
---
Directions: Write the force words that complete each sentence.
---
1. The greater the ________, the easier the object will move.
✔ Answer: *force*
🔹 Explanation: The more force applied to an object, the more it will accelerate (assuming mass is constant). So, greater force makes movement easier.
2. To do the job in less time and with less energy, use a ________.
✔ Answer: *machine*
🔹 Explanation: Machines help us do work more efficiently by reducing effort or changing the direction of force, often saving energy and time.
3. That rock will roll down the hill due to the force of ________.
✔ Answer: *gravity*
🔹 Explanation: Gravity pulls objects toward the Earth. On a slope, this causes rocks to roll downhill.
4. To make something ________, both ends need to have the same weight.
✔ Answer: *balance*
🔹 Explanation: For something to be balanced (like a seesaw), the forces or weights on both sides must be equal.
5. It takes ________ to get a job done.
✔ Answer: *energy*
🔹 Explanation: Energy is required to perform work. Without energy, no job can be completed.
6. ________ is the idea that something in motion will remain in motion, and something at rest will remain at rest, unless affected by an outside source.
✔ Answer: *inertia*
🔹 Explanation: This is Newton’s First Law of Motion — inertia is the tendency of an object to resist changes in its state of motion.
7. It would be more difficult to ________ a wagon if it didn’t have wheels.
✔ Answer: *pull*
🔹 Explanation: Wheels reduce friction. Without them, pulling a wagon would require much more effort.
8. If you have a few people ________ on the rope, the box will be easier to move.
✔ Answer: *pull*
🔹 Explanation: Multiple people pulling together increase the total force applied, making it easier to move the box.
9. ________’s theories on motion are still believed correct today.
✔ Answer: *Newton*
🔹 Explanation: Sir Isaac Newton formulated the laws of motion, which are foundational in physics and still widely accepted.
10. We added wheels to our bureau to create less ________.
✔ Answer: *friction*
🔹 Explanation: Wheels reduce friction between the object and the surface, making it easier to move.
