What type of friction occurs when air pushes against a moving object?

• surface area

• air resistance

• velocity

• gravity

What equation links weight, mass and g

• w = mg

• w = g/m

• w = m/g

• w = mgm

• w = 1/mg

A child pulls on a toy with a force of 25N to the right. Another child pulls the toy with 15N to the left. The resultant force is:

• 1.7N to the right

• 1.7N to the left

• 10N to the right

• 10N to the left

Which two forces are equal?

• The Weight (Force of Gravity) and the Normal Force

• The applied force and the Force of friction

• None

• The Force of Gravity and the Motion Force

The term for when an object speeds up, slows down, or changes direction
