Motion and Forces Worksheet - WordMint - Free Printable

Let's solve this matching exercise step by step. We are given a list of definitions (1–24) on the left and a list of terms/answers (A–X) on the right. The goal is to match each definition with the correct term.

Step-by-step Matching:

1. The downward pull on an object
→ This refers to gravity
✔ A. gravity

2. The force of gravity on an object
→ This is weight, which is the gravitational force acting on mass
✔ C. weight

3. The elliptical path that the moon follows around Earth
→ This is called an orbit
✔ R. orbit

4. A force that resists the motion between two surfaces in contact
→ This is friction
✔ D. friction

5. The friction due to air
→ This is air resistance
✔ F. air resistance

6. A measure of how much force is acting on a certain area
→ This is pressure
✔ S. pressure

7. The unit for pressure
→ The SI unit for pressure is pascal
✔ W. pascal

8. Pressure =
→ Pressure = force / area
✔ J. force/area

9. The upward force on objects in a fluid
→ This is the buoyant force
✔ U. buoyant force

10. States that an increase in speed of the motion of a fluid decreases the pressure within the fluid
→ This is Bernoulli’s Principle
✔ G. Bernoulli's Principle

11. States that when an outside pressure is applied at any point to a fluid in a container, that pressure is transmitted throughout the fluid with equal strength
→ This is Pascal’s Principle
✔ N. Pascal's Principle

12. The use of force to move an object some distance
→ This is work
✔ O. work

13. The unit to measure work
→ The unit of work is the joule
✔ T. joule

14. Work =
→ Work = force × distance
✔ M. force x distance

15. Energy in motion
→ This is kinetic energy
✔ X. kinetic energy

16. Energy being stored
→ This is potential energy
✔ K. potential energy

17. GPE =
→ Gravitational Potential Energy = mgh
✔ I. mgh

18. KE =
→ Kinetic Energy = (1/2)mv² → m x v² / 2
✔ Q. m x v2 / 2

19. ME =
→ Mechanical Energy = Potential Energy + Kinetic Energy
✔ V. PE + KE

20. The energy possessed by an object due to its motion or position (combining the object potential and kinetic energy)
→ This is mechanical energy
✔ P. mechanical energy

21. Energy that is able to be transferred or transformed into another type of energy is called
→ This refers to mechanical energy (since it can be converted between KE and PE), but more generally, energy itself has this property. However, based on the options, mechanical energy fits best as it is the sum of both forms. But actually, the statement is describing energy in general. But since "mechanical energy" is listed and matches contextually, we go with that. Wait — actually, the best fit here is P. mechanical energy, as it's the form that can be transformed between kinetic and potential.
✔ P. mechanical energy

*(Note: The phrasing is a bit ambiguous, but in physics, mechanical energy is the energy that can be transformed between KE and PE. So P is correct.)*

22. The rate at which you do work
→ This is power
✔ B. power

23. The unit of measurement for power
→ The unit of power is the watt
✔ E. watt

24. Power =
→ Power = work / time
✔ L. work/time

📝 Explanation Summary:

- Gravity pulls objects down.
- Weight is the force of gravity on an object (mass × gravity).
- Orbit is the path of one body around another (e.g., Moon around Earth).
- Friction opposes motion between surfaces; air resistance is a type of friction in air.
- Pressure = Force/Area; unit is pascal.
- Buoyant force pushes up on objects in fluids.
- Bernoulli’s Principle: Faster-moving fluid has lower pressure.
- Pascal’s Principle: Pressure applied to a fluid is transmitted equally.
- Work = force × distance; unit is joule.
- Kinetic energy (KE) = energy of motion; Potential energy (PE) = stored energy.
- Mechanical energy (ME) = KE + PE.
- Power = work/time; unit is watt.

All answers are consistent with standard physics terminology.
