What the 2025 Unit Test Paper Covers
The hosted paper is the UT1 Physics test from 2025. It tests the first few chapters of the Class 10 syllabus. The questions focus on work, energy, power, and uniform circular motion.
Part A carries 6 marks, with six one-mark questions. Part B carries 4 marks, with four one-mark questions. The paper tests conceptual understanding and basic derivations rather than long numerical calculations.
Topics Tested in the 2025 Paper
- Work done by a force: Conditions for positive and negative work, including examples.
- Uniform circular motion: The difference between centripetal and centrifugal forces.
- Gravitational work: Deriving the expression for work done by gravity on a falling mass.
- Satellite motion: Why a satellite in a circular orbit does zero net work.
- Energy conservation: Proving that the sum of kinetic and potential energy remains constant for a freely falling body.
- Kinetic energy changes: How kinetic energy changes when mass or velocity is altered.
How to Use This Unit Test for Exam Preparation
Use this paper to simulate a real exam. Sit at a desk without your textbook. Set a timer for 30 minutes. Attempt every question in order, just like you would in school.
After finishing, open your Selina Physics textbook and check your answers. Pay attention to the exact wording of definitions. In Physics, a missing unit or a skipped step can cost marks even if your final number is correct.
Study Order for Force and Work-Energy
- Chapter 1 (Force): Learn moments, torque, and equilibrium first. You need these basics to understand circular motion.
- Chapter 2 (Work, Energy, Power): Memorise the formulas W = FS \cos \theta and W = mgh. Practice the special cases where the angle is 0 or 90 degrees.
- Attempt the unit test: Once you can write the definitions from memory, try the 2025 paper.
Common Mistakes Students Make on This Paper
| Mistake | Correct Rule |
|---|---|
| Saying a satellite does work because it moves. | Work needs force and displacement in the same direction. The centripetal force is perpendicular to the satellite’s motion, so work is zero. |
| Forgetting units in the work done by gravity derivation. | The expression W = mgh yields Joules. Always state the unit. |
| Confusing centripetal and centrifugal forces. | Centripetal force pulls inward toward the center. Centrifugal force is an apparent outward force seen from a rotating frame. |
| Writing that kinetic energy doubles when velocity doubles. | Kinetic energy depends on velocity squared. If velocity doubles, kinetic energy becomes four times larger. |
Worked Example: Energy Conservation for a Falling Body
The 2025 paper asks you to prove that total mechanical energy is conserved for a body falling from height h. Here is how to structure your answer.
Let a body of mass m fall from rest at height h. Let the ground be the reference level where potential energy is zero.
- At the top (before falling): Velocity is zero. Kinetic energy is zero. Potential energy is mgh. Total energy is 0 + mgh = mgh.
- After falling a distance x: The new height is (h – x). Using the third equation of motion, velocity squared is v^2 = 2gx. Kinetic energy is \frac{1}{2}mv^2 = mgx. Potential energy is mg(h – x). Total energy is mgx + mg(h – x) = mgh.
- At the ground: Height is zero. Potential energy is zero. Velocity squared is v^2 = 2gh. Kinetic energy is \frac{1}{2}m(2gh) = mgh. Total energy is mgh + 0 = mgh.
Since the total energy equals mgh at all three points, mechanical energy is conserved. Practice writing these steps clearly, as the examiner looks for the intermediate equations.
Marking Guidance for One-Mark Questions
The 2025 paper uses one-mark questions. You must be brief and precise. A one-mark answer needs the core rule or formula, not a full paragraph.
- State the condition: Write the exact physical condition. For example, work is positive when force and displacement are in the same direction.
- Give the reason: State the physical principle. For the satellite question, write that centripetal force is perpendicular to displacement.
- Derive the expression: Show the substitution. Start with W = F \times S, replace F with mg and S with h, and state the final result.
