The placebo effect refers to the response that individuals can have to a treatment just because they are expected to have one, even when they are not given any treatment at all. The purpose of conducting an experiment is to find evidence to decide whether that cause-and-effect relationship exists or not, but how exactly do you do this? The horizontal motion has zero acceleration which makes the horizontal component of the velocity constant. Data collected from the experiment are used to create the graph of the magnitude of the applied force exerted on the object as a function of time is shown.
