Ana is pushing a wheelbarrow of rocks. She stops and unloads half of the rocks. How will this effect the force needed to move the wheelbarrow?

• Gravity is decreased, making the wheelbarrow harder to move.

• Gravity is increased, making the wheelbarrow easier to move.

• Mass is decreased, making the wheelbarrow easier to move.

• Friction is increased, making the wheelbarrow harder to move.
