Played 0 times. Calculating Net Force. The plane is moving, but if both forces are the same magnitude, then there is zero net force and the plane will continue traveling along that path until there is a net force. If gravity is pulling down with 600 N and air resistance is pushing up with only 200 N, then 600 - 200 = 400, so we have 400 N downward as our net force. Create your account, 16 chapters | One pound is equal to .453 kg, so you'll need to multiply that value by your 8 pounds to determine the mass. You … So if we return to our first example of 5 N of force acting on an object both to the left and the right, our free-body diagram would be a box in the middle with two equal-sized arrows, one pointing left and the other pointing right.
