Give another example of Inertia:

Multiple Choice

What is Newton's First Law known as? The Law of

• Friction

• Inertia

• Mass

• Gravity

Multiple Choice

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

• motion

• inertia

• mass

• rest

Multiple Choice

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

Multiple Choice

Which has more Inertia? (so need more force to move)

• Truck

• Ant

• Cat

• A skateboard

Multiple Choice

If one object has twice as much mass as another object, it also has twice as much...

• velocity

• inertia

• acceleration due to gravity

• DO NOT PUSH ME

Multiple Choice

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

Multiple Choice

Objects with greater _________ also have greater inertia.

• speed

• mass

• friction

• temperature

Multiple Choice

What is Newton's First Law

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• An object at rest stays in motion, an object in motion stays in rest

Multiple Choice

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

• kinetic energy

• inertia

• net force

• vector

Multiple Choice

. Balanced or unbalanced?

• balanced

• unbalanced

Multiple Choice

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.

Multiple Choice

If an object is not moving the forces acting upon it are

• unbalanced

• weak

• balanced

• HULK SMASH!

Multiple Choice

An object in motion tends to stay in motion unless an ___ force acts on it.

• unbalanced

• balanced

Multiple Choice

Which type of force(s) will cause a change in an object's motion?

• gravity

• zero net force

• balanced forces

• unbalanced forces
