Let's solve each sentence in the "Forces & Motion" worksheet using the provided word bank:
Word Bank:
- push
- pull
- gravity
- friction
- force
- inertia
- machine
- energy
- balance
- Newton

1. The greater the ____________ the easier the object will move.
✔ Answer: *force*
Explanation: The greater the force applied to an object, the more it accelerates (according to Newton’s Second Law), making it easier to move.
---
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 the amount of effort needed or changing the direction of force, saving time and energy.
---
3. That rock will roll down the hill due to the force of ____________
✔ Answer: *gravity*
Explanation: Gravity is the force that pulls objects toward the Earth, causing the rock to roll downhill.
---
4. To make something ____________ both ends need to have the same weight.
✔ Answer: *balance*
Explanation: For something like a seesaw to be balanced, the weights on both sides must be equal so there is no net torque.
---
5. It takes ____________ to get a job done.
✔ Answer: *energy*
Explanation: Energy is required to perform work (a "job"). Without energy, no movement or change can occur.
---
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 — the concept of inertia describes this behavior.
---
7. It would be more difficult to ____________ a wagon if it didn’t have wheels.
✔ Answer: *pull*
Explanation: Without wheels, you’d have to drag the wagon across the ground, which increases friction. Wheels reduce friction, making pulling easier.
---
8. If you have a few people ____________ on the rope, the box will be easier to move.
✔ Answer: *pull*
Explanation: More 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 ____________ when we move it.
✔ Answer: *friction*
Explanation: Wheels convert sliding friction into rolling friction, which is much smaller, making it easier to move heavy objects.
---
✔ Final Answers:
1.
force
2.
machine
3.
gravity
4.
balance
5.
energy
6.
inertia
7.
pull
8.
pull
9.
