Newton’s Three Laws of Motion, Explained With Everyday Examples
Newton’s first, second and third laws of motion explained simply, with everyday examples, the F = ma formula, worked problems and common misconceptions.
Topic
Mechanics
Motion, forces, energy and momentum, explained with examples.
Kinetic vs Potential Energy (With Examples)
Kinetic and potential energy explained: formulas, units, everyday examples, energy conversion on roller coasters and pendulums, and a quick energy calculator.
Momentum Explained With Examples
Momentum explained simply: p = mv, conservation of momentum in collisions and explosions, impulse and why crumple zones and airbags work, with worked examples.
Centripetal Force Explained
What centripetal force is, the formula F = mv²/r, what provides it in cars, planets and fairground rides, why “centrifugal force” feels real, and examples.
Speed, Velocity and Acceleration
Speed, velocity and acceleration explained: scalars vs vectors, formulas, units, reading distance-time and velocity-time graphs, and worked examples.
Work, Energy and Power Formulas
Work, energy and power explained: W = Fd, P = W/t, units like joules and watts, efficiency, and worked examples from lifting boxes to climbing stairs.
Friction Explained
What friction is, static vs kinetic friction, the formula F = μN, coefficients of friction, how friction helps and hurts, and examples from brakes to ice.
