Question

name the quantity that represents change in velocity pf body with time. is it scalar or vector quantity? Also mention its SI unit​

Answer 1

Solution :

$\bigstar \: \underline{ \boxed{ \bold{ \sf{ \large{ \red{Acceleration : }}}}}}$

• Acceleration is defined as ratio of change in velocity to the time interval.
• Acceleration is a vector quantity.
• SI unit of acceleration is m$\sf{s^{-2}}$
• Acceleration has both magnitude and direction.
• Acceleration can be positive, negative and zero.
• Magnitude of acceleration for uniform motion is equal to zero.
• Kinematics equations are only applicable for uniform acceleratory motion.
• Projectile motion is an example of uniform acceleratory motion.
