Forces Investigation Frame
This Wordbar supports writing an outline of an investigation in which students observe the frictional forces on a mass being pulled down a slope of different gradients.
The set contains a starter tab, a frame and relevant vocabulary to write up the investigation. To complete the test, attach mass weights to a force meter on a ramp. Pull the mass along the ramp using the force meter. Record the force needed to start the mass moving. Then increase the height of the ramp to make the gradient steeper at 10cm intervals and measure the force each time.
