A force caused by rubbing between two objects

• friction
• energy
• motion
• gravity

What is "g-force"?

• force measured in grams
• a special X-Team member who fights the forces of evil
• short for gravitational force; it is equal to the force exerted on an object by the Earth's gravity at sea level
• a weak force caused by lack of strength

How is speed measured?

• how fast the object arrives at its destination
• how far an object travels multiplied by the time it takes 
• the distance an object travels divided by the time it takes
• how fast object moves compared to another object
