• magnetism
• gravity
• repulsion
• friction

The only force acting upon the object is gravity

• free fall

• mass

• gravity

• friction

When objects fall through the air
** more surface area = the greater the air resistance **

• less surface area
• Air resistance

• water resistance

• same surface area

An object that is thrown

• Projectile
• Boomerang
• Feather
• Anchor

The force the one surface exerts on another

• pressure
• velocity
• friction

• density

Solid surfaces slide over each other

• bounce
• stick
• friction

• Silding friction

An object that moves through a liquid or gas

• fluid friction

• sliding friction

• gass friction

• friction

An object rolls over a surface

• sliding friction

• liquid friction

• rolling friction

• friction

The total momentum of the objects in an interaction is the same before and after the interaction

• Law of conservation
  Of momentum:

• Depends on the speed
• Sometimes true
• False
