Force
True or False: An unbalanced force means the motion of the object is not changing.
What is false.
What is density.
What is the formula for density?
What is D=Mass/Volume
What directions do we associate with moments?
What are anticlockwise and clockwise.
How do we refer to objects that have as many protons as electrons.
What is neutral.
What unit is force measured in?
What are newtons.
What two units do we often use for density (hint: one is for solids, and one is for liquids)?
What is g/mL and g/cm^3.
What are Newton-meters
An object is said to be charged if it lost or gained these particles.
What are electrons.

Does a penguin with smaller or bigger feet sink further into the snow?
What is smaller feet.
In a density column, liquid A sits at the top and liquid B sits at the bottom. Which liquid is less dense?
What is A.
What do we call the point around which the object rotates or turns?
What is the pivot.
What do we call the buildup of electric charges on the surface of a material?

What is 45 Nm.
What is static electricity caused by?
