‘The prop engine has been replaced with two 1,800-newton thrust rocket engines.’
‘A newton has a mass unit of kilograms and an acceleration unit of meters squared per second.’
‘Timber can usually soften and take about 100 kilograms, 1,000 newtons per square centimetre.’
‘The foot pad has an area of about 100 mm and can produce 10 newtons of adhesive force (enough to support two pounds).’
