Laws of Motion — Class 11 Maharashtra HSC Physics revision notes
A 7-page visual revision sheet for Laws of Motion, written for Class 11 Maharashtra HSC Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Laws of Motion sheet covers
- Aristotle's fallacy
- First law
- Second law
- Third law
- What each law actually establishes
- Momentum, and the case where mass itself changes
- momentum
- second law, general
- constant mass, dm/dt = 0
- Inertial and non-inertial frames
- The four fundamental forces
- Gravitational
- Electromagnetic
- Strong nuclear
- Weak nuclear
- Contact vs non-contact forces
- Non-contact
- Contact
- Real force vs pseudo force
- Apparent weight in a lift
- lift accelerating upward, a
- lift accelerating downward, a
- lift at constant velocity, a=0
- Conservative and non-conservative forces
- Work-energy theorem
- work by a variable force
- conservative force only, PE lost becomes KE gained
- a non-conservative force also present
- Impulse
- impulse, the change in momentum itself
- constant force acting for time Δ t
- varying force
- Conservation of linear momentum
- Elastic vs inelastic collisions
- Elastic
- Inelastic
- Coefficient of restitution
- definition, e always between 0 and 1
- perfectly elastic
- perfectly inelastic, v_1=v_2
- Final velocities after a head-on elastic collision
- body 1 after collision
- body 2 after collision
- Head-on elastic collision, equal masses
- Torque, the rotational analogue of force
- Couple
- Moment of a force vs moment of a couple
- Single force
- Mechanical equilibrium
- Stable, unstable, neutral equilibrium
- Stable
- Unstable
- Neutral
- Centre of mass
- Centre of gravity
- Symbols
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Laws of Motion the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
