During a time interval of one second, a ball moves in the +*x* or -*x* direction (that is, to the right or the left), and a net force acts on the ball in the +*x* or -*x* direction. For each motion listed below, check ** all** the descriptions of net force that could produce that behavior. More than one description may be valid for a particular motion.

(b) ball moving to the right at constant speed

net force to the right with increasing magnitude

net force to the right with decreasing magnitude

net force = 0

net force to the right with constant magnitude

net force to the left with increasing magnitude

net force to the left with decreasing magnitude

net force to the left with constant magnitude

(c) ball moving to the left at constant speed

net force to the right with constant magnitude

net force = 0

net force to the left with constant magnitude

net force to the right with increasing magnitude

net force to the right with decreasing magnitude

net force to the left with decreasing magnitude

net force to the left with increasing magnitude

Step 1

(b) **Ball moving to the right at constant speed:**

If a ball is moving at a constant speed, it simply means that acceleration of the ball is zero. And according to Newton’s second law, we can say that if the net acceleration of a body is zero, then the net force must be zero.

I.e. F = ma, so if net acceleration ‘a’ is zero, then the net Force ‘F’ must be zero as well.

So, for a ball moving to the right at constant speed, the net force is zero.

Step 2

(c) **Ball moving to the left at constant speed:**

If a ball is moving at a constant speed, it simply means that acceleration of the ball is zero. And according to Newton’s second law, we can say that if the net acceleration of a body is zero, then t...
