How does newton’s 3rd law of motion account for the lift of an airplane wing? a) the shape of the wing lowers gravity on the plane. b) the shape of the wing increases the density of the air, so it is heavier than the wing. c) the air follows the curve of the wing and is thrown downward. d) there is less pressure on top of the wing than there is below the wing.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
