What is motion?
• where the object is located
• how fast an object moves
• the amount of space between two objects
• when an object moves from one place to another

Speed is__________.

• the total space an object takes up
• the changing direction of an object
• the amount of space between two objects
• how fast an object can move

Direction is__________.

• the amount of space an object takes up
• the amount of space between objects
• the way an object is moving
• the measurement of the force moves an object
What is distance?
• an observation of the direction an object is moving
• the amount of space between objects
• a description of where an object is located
• the amount of force needed to move an object
Position is__________.
• the measurement of the speed of an object
• the amount of friction between two objects
• where an object is located
• the ability of an object to change direction
Force is__________.
• two objects rubbing together
• objects that are not moving
• a push or pull that makes something move
• the way an object is moving
What is gravity?
• the measurement of how fast an object moves
• a push or pull that makes something move
• a force that makes objects slow down or stop moving completely
• the force that pulls objects down toward the center of the Earth
What is the definition of friction?
• a push or pull that makes something move
• a force that makes objects slow down or stop moving
• a force that makes objects move faster
• the way an object is moving
Members of a wilderness club are setting up their tents at a campground. The group needs to move rocks out of the way. They will have to use __________.
• gravity
• friction
• force
• speed
Gillian is pulling a cart filled with her favorite toys as she walks to the beach. What will happen when the path turns from wooden boardwalk to sand?
• It will be less difficult to pull the cart, because the sand will cause less friction.
• It will be just as easy to pull the cart on the sand, because the amount of friction will stay the same.
• It will be less difficult to pull the cart, because the sand will cause more friction.
• It will be more difficult to move the cart, because the sand will cause more friction.
