Definition of Physics.
Distinction between physical and chemical phenomena.—Iron heated, Iron rusted. Candle melted, Candle burnt, etc., etc.
Motion. Force. Illustrations of familiar forces.—Muscular force. Force of stretched spring, etc., etc.
Consideration of some particular forces.—Gravity. Friction. Cohesion.
Gravity.—Distinction between body’s weight and mass. Weight is the earth’s pull upon it. Might be different while body unaltered. Centre of gravity. Experimental determination for laminæ of various shapes. Stable, unstable and neutral equilibrium dependent on position of centre of gravity. Everyday illustrations. Stick balanced on finger, etc.
Friction.—Everyday instances. Effect if it were removed.
Cohesion.—Three states of matter. Solids. Liquids. Gases. Essential difference between them. Experiments showing retention of size and shape by solids, of size by liquids, of neither by gases.
Pressure of Liquids—
