A Truck moves with a constant Velocity are the forces acting on it balanced? Justify your response.
What is Yes? No acceleration therefore net force=0, forces are balanced.

An object is kicked off a cliff. What happens to the horizontal and vertical velocity over time? Ignore air resistance.
Horizontal velocity remains constant, vertical velocity will increase.
