Question

Activity 9.5 Squashing foam for You can squash a piece of plastic foam by applying pressure to it. Place a stiff piece of wood on top of the foam. Place weights on top of the wood. There are three things to measure: • the area of the wood pressing down on the foam • the force pressing down on the foam • the thickness of the foam as it is squashed. Calculate the pressure acting on the foam. Use different weights to change the pressure. Draw a graph to show how the thickness of the foam depends on the pressure.
