Question

write an activity to define acceleration

Answer 1

Before we can talk about acceleration, we need to understand velocity which is the rate that an object moves from one place to another. Velocity is a vector quantity, which means it has both a magnitude, called speed, and a direction.

Acceleration, also a vector quantity, is the rate at which an object changes its velocity

Answer 2

An object moves 10meter per second. The object speeds up and now is moving north at 15 meter per second. The object has accelerated.
