iacle the correct word or phrase in each bold pair in the sentences below. Dressure is a measure of how much force / mass is exerted over a certain volume / area. If the force applied to a certair area is bigger the pressure will be smaller / bigger. It you increase the rpa over which a force is exerted the pressure will be smaller / bigger. You can calculate pressure sing the equation force divided by area / area divided by force. You can measure pressure in newtons / pascals, 1 Use this equation to work out the pressure: - A box weighs SO N. Its base has an area of 5 m?. What pressure does it exen? b Another identical box is plaCed on top of the first box. What is the pressure now? e A snowboarder weighs 300 N. The area of the snowboard is 0.5 m. What is the pressure on the snow? 3 A student is investigating the pressure that a block uf wood is exerting on the floor. The weight of the wood is 20 N. The block is 10 cm long, 5 cm wide, and 2 cm high. a What is the biggest pressure that the block can exert on the floor? b What is the smallest pressure that the block can exert on the floor? E Copy the table. Use the equation above to complete the table. Remember to use the correct units for pressure and area. Force (N) Pressure Area 20 4 cm 60 1.5 N/m? 0.05 N/m 15 N/cm 12 75
