Addie tosses a ball straight upward, in the positive direction. The ball falls freely under the influence of gravity.

At the highest point in the ball’s motion,

• its velocity is zero and its acceleration is zero.

• its velocity is zero and its acceleration is positive (upward).

• its velocity is zero and its acceleration is negative (downward).

• its velocity is positive (upward) and its acceleration is zero.

• its velocity is positive (upward) and its acceleration is zero.

Camden and Ella are pushing a box from opposite sides with equal force, so the box does not move. What do we call the forces acting on the box that combine and form a net force of zero?

• velocity

• centripetal force

• balanced forces

• acceleration

Emma and Anthony are pushing a box from opposite sides. If the forces they apply combine and form a net force that is not zero, what are these forces called?

• balanced forces

• unbalanced forces

• acceleration

• velocity
