Adam is trying to hang a new clock in his apartment. The clock experiences a force due to the gravity of 15N. He has a stick on a hook that exerts an upward force of 10N. Are the forces on the clock balanced or unbalanced and what will happen to the clock?

• The forces are unbalanced and the clock will fall

• The forces are balanced, but the clock will fall

• The forces are unbalanced and the clock will fly upward

• The forces are balanced and the clock will stay put

What force slows objects down and keeps them from moving?

• Gravity

• Friction

• Net Force

• Acceleration
