Verified answer
1. in everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity.
2. The main difference between velocity and acceleration
velocity and acceleration both use speed as a starting point in their measurements. speed, which is the measurement of distance traveled over a period of time, is a scalar quantity. .. acceleration the rate of velocity change over time.
3. Letter C
EXPLANATION: a student running around the track oval at constant speed is a accelerating.
