process. There are no free charges that can move to produce a current. (3) 3.2 3.2.1 The higher the concentration of ions in a solution, the greater the current through the solution. 3.2.2 The type of substance affects the current in that some ionic substances dissolve to a greater extent than others, thereby releasing more ions in
Speed is the rate at which an object moves. Velocity is the speed of an object in a particular direction. In your groups of three, discuss and write down the procedure to determine the average speed of your toy car. Give students 15 minutes in their group to come up with lab procedures.

Jun 17, 2019 · Calculate the instantaneous velocity given the mathematical equation for the velocity. Calculate the speed given the instantaneous velocity. We have now seen how to calculate the average velocity between two positions.
word speed when describing any velocity. • Speed is a scalar quantity (it doesn't have direction). • We usually want the velocity of an object, since velocity is a vector. That means we also know the direction the object is traveling. What speed did you drive today along Yellowhead? I drove at 72km/h.
