7.7D Newton's First Law of Motion

Multiple Choice

Which of the following best describes inertia as explained by Newton's First Law of Motion?

• The tendency of an object to resist changes in its state of motion

• The force that causes objects to accelerate

• The energy stored in moving objects

• The ability of objects to attract each other

Multiple Select

Which of the following statements are true about objects in motion and at rest?

• An object in motion stays in motion unless acted on by a force

• An object at rest stays at rest unless acted on by a force

• Objects always change motion without any force

• Objects at rest will eventually start moving on their own

Multiple Choice

What is inertia?

• An object's resistance to a change in motion

• The force that moves an object

• The speed of an object

• The direction an object moves

Multiple Choice

According to the images, what does it take more force to do?

• Change the motion of an object with a large mass

• Change the motion of an object with a small mass

• Keep an object at rest

• Make an object lighter

Open Ended

Explain how mass affects the amount of force needed to change an object's motion, using examples from the images.

Multiple Choice

Which of the following best describes mass?

• The amount of matter in an object

• The weight of an object

• The size of an object

• The color of an object

Multiple Select

Select all statements that correctly describe inertia.

• It is the tendency of an object to resist a change in motion

• It depends on the mass of the object

• It is also known as Newton's first law

• It only applies to objects at rest

Multiple Choice

How are mass and inertia related according to the information presented?

• Objects with more mass have more inertia

• Objects with less mass have more inertia

• Mass and inertia are not related

• Inertia only applies to moving objects
