Speed, Velocity and Motion Graphs for SS 1
Speed measures distance travelled per unit time, whereas velocity includes direction. The gradient of a distance-time graph indicates…
Rectilinear Acceleration and Equations of Motion for SS 1
Acceleration is the rate at which velocity changes. For constant acceleration, equations connect initial velocity, final velocity, time…
Scalar and Vector Quantities and Their Differences for SS 1
Scalars such as mass and time have magnitude only. Vectors such as force and displacement have both magnitude…
Fluids, Surface Tension, Viscosity and Fluid Flow for SS 1
Surface tension makes liquid surfaces resist stretching, while viscosity resists flow. Fluid speed and behaviour depend on these…

Conservation principles
Work, Energy, Power and Energy Conservation for SS 1
Work occurs when a force causes displacement; power measures the rate of energy transfer. Energy changes form but…
Temperature, Thermal Expansion and Heat Energy for SS 1
Heat is energy transferred because of a temperature difference. Heating may raise temperature or cause expansion, depending on…

Meaning, Types and Properties of Force Fields for SS 1
A force field is a region where an object experiences a force without contact. Gravitational, electric and magnetic…
Gravitational Field, Free Fall and Acceleration Due to Gravity for SS 1
Gravity attracts masses towards one another. Near Earth's surface, freely falling objects accelerate at about 9.8 m/s² when…
Electric Fields, Field Lines and Electric Forces for SS 1
An electric field surrounds a charge and exerts forces on other charges. Field lines point from positive to…
Magnetic Fields, Poles and Magnetic Field Lines for SS 1
A magnetic field surrounds a magnet or current-carrying conductor. Field lines run from north to south outside a…
