What is a force that opposes motion between two surfaces?

• friction
• acceleration
• velocity
• motion

What is inertia?

• the tendency of an object to resist change in motion
• how fact an object is going in a given direction
• a measure of the lack of motion of an object
• change in speed or direction of an object

What is the difference between mass and weight?

• mass is how much matter is in an object, and weight is the gravitational pull on that object
• mass and weight are the same
• weight affects how much mass is in an object
• weight is determined by how many atoms make up an object
