.) What is meant by (1) average speed, and (ii) unifos​

Answer 1

Answer:

the action or process of moving or being moved.

the rate at which someone or something moves or operates or is able to move or operate. SI meter per second

the total distance traveled divided by the total time elapsed.

Answer 2

Answer:

here is your answer plz mark me as brainliliest

Explanation:

motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

examples:-Motion of a simple pendulum.

Motion of a simple pendulum.Motion of a moving bicycle.

Motion of a simple pendulum.Motion of a moving bicycle.Motion of a flying mosquito.

Motion of a simple pendulum.Motion of a moving bicycle.Motion of a flying mosquito.Motion of a merry-go-round.

speed:-Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Higher speed means an object is moving faster

SI UNIT OF SPEED : meter per second
