Newton's Law of Motion

The tendency of an object to resist a change in its motion is:

• acceleration
• inertia
• mass
• frame of reference

Objects with greater _________ also have greater inertia.

• speed

• mass

• force

• friction

Which has more mass, a kilogram of feathers or a kilogram of iron?

• The feathers

• The iron

• Neither

• It depends

Friction is a force that always acts

• perpendicular to an object's motion

• opposite to an object's motion

• in the same direction as an object's motion

• parallel to the object's motion

How does acceleration of an object change relation to its mass? It is

• directly proportional

• inversely proportional

• acceleration doesn't depend on mass at all

• directly to square root
