Question

can anyone plz explain all the kinds of basic physics like what is velocities , acceleration etc??​

Answer 1

Answer:

velocity is defined as the speed at which something moves in particular direction

the SI unit is m/s

Acceleration is vector quantity that is defined as the rate at which an object change its valocity

now Mark me as brilliant

Answer 2

Answer:

Velocity: The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.

• SI base unit: m/s

Acceleration: Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

•SI unit: m/s2, m·s−2, m s−2

Hope it helps you and plzzzz mark as brainliest..!!!
