scalar and vector

• distance is the total length of path covered from one point to another
• displacement is the shortest distance covered by an object from the initial position to the final position
• average speed is the result when you divide the distance by the time
• $velocity =$$displacement / time$
• $speed =$$total distance/time$
• $Aave =$$change in velocity / time$
• $Aave =$$vf-vi / t$
• quantities that require both magnitude and direction is called vector quantities
• quantities that do not require both magnitude and direction are called scalar quantities
• scalar quantities are time, mass, distance, speed, temperature, area, volume, density
• vector quantities are displacement, velocity, acceleration, force, momentum, and impulse
• acceleration is the change in velocity per unit time
