"Terminal velocity" is the velocity at which _____

• point at which a falling object hits the ground
• the point at which an object can no longer accelerate
• the point at which an object lifts off the ground and flies
• the point at which any object stops

A measure of the gravitational force exerted on an object

• newton
• weight
• free fall
• inertia

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
