you experience more drag, when you are driving at 20 mph or 70 mph? Based on the information given above about the drag, explain your answer. How does the drag force acting on your hand change when accelerating from 20 mph to 70 mph?
To better understand the concept of non-constant force, in this case of the drag force, think of when you are driving your car and put your hand outside of the window (don’t do it though, it might be risky). When do you experience more drag, when you are driving at 20 mph or 70 mph? Based on the information given above about the drag, explain your answer. How does the drag force acting on your hand change when accelerating from 20 mph to 70 mph?
Experimentally it has been found that drag force acting on a body depends on the velocity of that body. And for low speed this drag force is found to be proportional to velocity of body i. e., Fdrag = k v. And for very high value of velocities, it is found to be proportional to square of velocity, i. e., Fdrag = k v2.
