Which graph best represents the relationship between the acceleration of an object falling freely near the surface of Earth and the time that it falls?
"what is graph 4"
300
What is the difference between a scalar and vector quantity
"what is Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction."
