The location of an object in relation to another object or place is described as 

• friction 
• gravity 
• velocity 
• position 

Cars, bicycles, and people are all objects that can be in motion. What is true about motion? 

• an object in motion is accelerating 
• motion is the change in position of an object. 
• an object in motion has no speed but it does have velocity
• gravity and friction are responsible for all motion

A boy is pulling a box across the floor.  How is friction acting on the box? 

• friction holds the box down 
• the force of friction slows the box down and acts against the direction the boy is pulling it
• frictions speeds up the motion of the box
• Friction increases the speed of the boat
