Position, Distance and Displacement on the Coordinate Plane for SS 1
Distance is the total length travelled, while displacement gives the straight-line change in position and direction between starting…
Time Measurement, Units and Measuring Instruments for SS 1
Time is measured in seconds using clocks, stopwatches and timers. Accurate experiments require suitable instruments and consistent timing…
Electric Charge, Charging Methods and Electrostatics for SS 1
Electric charge may be positive or negative. Friction, contact and induction redistribute charge; unlike charges attract and like…
Motion, Types of Motion, Forces and Friction for SS 1
Motion is a change in position over time; forces can alter movement. Friction opposes relative motion and may…
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…
