Let's solve this vocabulary matching worksheet step by step. The task is to fill in the blanks with the correct term from the provided word bank based on the definitions.
---
Word Bank:
gravity, fulcrum, inertia, energy, force, gears, kilogram, lever, machine, motion, mass, lubricant, potential, friction, windmill, pulley, weight, speed
---
Now, let's go through each definition and match it to the correct term:
---
1.
__________ changes the speed, direction or shape of an object by pushing or pulling.
- This describes a
force — a push or pull that can change an object’s motion.
-
✔ Answer: force
---
2.
__________ is the force that stops something from moving (or really slows it down) when it comes in contact.
- This refers to
friction, which opposes motion between surfaces in contact.
-
✔ Answer: friction
---
3.
__________ is the still point of a simple machine.
- In a lever, the
fulcrum is the fixed point around which the lever rotates.
-
✔ Answer: fulcrum
---
4.
__________ There are many kinds of this: potential, electrical, light and heat. Each kind does work by moving molecules over a distance.
- This describes
energy, which comes in various forms and involves movement of molecules.
-
✔ Answer: energy
---
5.
__________ are wheels that are found in machines; they have pieces (cogs) jutting out from them and hook into another wheel to make it spin.
- These are
gears, which transfer motion between rotating parts.
-
✔ Answer: gears
---
6.
__________ is a force of attraction pulling objects toward the Earth and to each other.
- This is
gravity, the natural force attracting objects with mass.
-
✔ Answer: gravity
---
7.
__________ is a word describing the condition of objects remaining as they are in motion or at rest unless a force acts upon them.
- This is
inertia, described by Newton's First Law of Motion.
-
✔ Answer: inertia
---
8.
__________ is a unit of mass used in science.
- The standard unit of mass in science is the
kilogram.
-
✔ Answer: kilogram
---
✔ Final Answers:
1.
force
2.
friction
3.
fulcrum
4.
energy
5.
gears
6.
gravity
7.
inertia
8.

🔍 Explanation Summary:
-
Force: Any push or pull that changes motion.
-
Friction: Resists motion between touching surfaces.
-
Fulcrum: Pivot point in a lever.
-
Energy: Capacity to do work; exists in many forms.
-
Gears: Toothed wheels that transmit motion.
-
Gravity: Attractive force between masses.
-
Inertia: Resistance to change in motion (Newton’s 1st Law).
-
Kilogram: SI unit for measuring mass.
These terms are foundational in understanding
force and motion concepts in physics.
