The fluid friction experienced by falling objects through the air like leaves floating down from trees:

• Gravity

• Friction

• Air Resistance

• Inertia

What type of surface produces LESS friction causing you to slip and fall?

• Smooth surfaces like ice

• Rough surfaces like a sideway

Equal forces acting on an object in opposite directions; the object will not move:

• Unbalanced forces

• Balanced forces

• Gravity

• Friction

Which of the following statements would be an example of a BALANCED force?

• A soccer ball rolls across the grass after being kicked.

• A baseball flies through the air.

• A cell phone falls out of your hand.

• A book sits on a table without moving.

Near a sea or ocean, an earthquake could cause a

• hurricane

• tornado

• tsunami
