Pre-Lab Questions 1. This lab contains two different experiments that cover two different aspects of friction. In your own words, describe both concepts and how each experiment demonstrates them. The two aspects of friction are static Friction and kinetic friction. Static Friction is the force that is put on an object to return to rest after it has been moved from an initial position. Certain objects can be heavy enough in mass to where the friction of the object keeps it in place, lifting ...

scalar quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) the speed and direction of a body's motion, the rate of change of position (an a...
