Which describes an object’s speed in free fall? the object accelerates until it reaches its terminal velocity. the object falls at a constant speed because only one force acts on it. the object falls faster and faster until it strikes the ground. the object speeds up and then stops when air resistance equals gravity.

the only thing that influences a free fall is gravity. air resistance can change how an object falls. an object falling continues to accelerate because of gravity in other words as long as there is no air resistance it will continue falling faster and faster. my explanation is because of newtons third law, for every action there is an oposite and equal reaction. in other words the earth will pull the object and the object will pull the earth. a fun fact is because the moon pulls on the earth the moon is actually the cause of tides.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
