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

• inertia
• kinetic energy
• vector
• net force

Objects with greater _________ also have greater inertia.

• speed
• mass
• temperature
• friction

The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

An object following a straight-line path at a constant speed 

• has zero acceleration
• has no forces acting on it
• has a net force acting in the direction of motion
• none of these

If a hockey puck slides on a frictionless force it will eventually slow down because of its inertia.

• True
• False

Why is the net force 0 in the image?

• Because the elephants are the same size
• Because they are both pulling the same amount of force in opposite directions
• Because they are elephants
• Because they are pulling away from each other.
