Name:BevelUses:This instrument is suitable for grouping students in elementary school science. It can be used together with instruments such as trolleys to complete the series of related experiments on "sports and force" and related slopes.Structure:The instrument is composed of inclined panels and brackets.Operational useInstallation of the instrument:Insert the bracket behind the inclined panel to make the inclined panel and the horizontal slope (the slope can be adjusted as needed), so that the installation can be completed.Experiment 1:The effect of friction on the motion of the object.Experiment 2: Moving objects have inertia.Lab 3: A stationary object has inertia.Experiment 4: Moving objects have kinetic energy.PrecautionsBefore you can fold the bevel, you should pull out the plastic sheet and then fold the inclined panel.The instrument should be stored in a dry, ventilated, cool, non-corrosive manner.
