At the top of the hill, the force of gravity on A, compared with that on B, will be greater. Three books, X, Y, and Z, rest on a table as shown in the diagram. The weight of each book is indicated. The net or unbalanced force acting on book Y is 4 N down. 5 N down.
Rockets do accelerate in outer space.
Miles Tugo is driving down the highway and a bug spatters into the windshield. Paul deTrigga fires a rifle. The rifle recoils from firing the bullet. The acceleration of the rifle's recoil is small because the force against the rifle is less than the force against the bullet. In order to catch a ball, a baseball player moves his or her hand backward in the direction of the ball's motion.
