If an object is balanced, but moving, what kind of speed is it? (accelerating, decelerating, constant...)

What is friction?

• Friction is a force that works against motion.

• Friction is a force that works alongside motion.

• Friction does not affect motion whatsoever.

What is the formula for measuring mass?

• Weight (N) = Mass (g) / 100

• Weight (N) = Mass (g) * 100

• Mass (N) = Weight (g) * 100

• Mass (N) * 100 = Weight (g)

How many grams does one kilogram have?

• 100

• 1000

• 10

• None

What is Weight?

• amount of matter in an object. (stuff you are made up of)

• measurement of the force of gravity acting on an object.
