The data table below lists the masses and speeds of four objects.
 

**Object**

**Mass (kg)**

**Speed (m/s)**

A

4.0

6.0

B

6.0

5.0

C

8.0

3.0

D

16.0

1.5


Which object has the greatest inertia?

A.Object A

B.Object B

C.Object C

D.Object D


Inertia is the tendency of an object to resist changes in its state of motion, which is directly related to its mass. The greater the mass of an object, the greater its inertia.

From the data provided:

- Object A: 4.0 kg
- Object B: 6.0 kg
- Object C: 8.0 kg
- Object D: 16.0 kg

**Object D** has the greatest mass (16.0 kg), so it also has the greatest inertia.

**Answer: D. Object D**

If you have any questions or need further details, let me know! Here are some follow-up questions you might consider:

1. How does speed affect an object's inertia?
2. What are some real-life examples of inertia?
3. How can we calculate the momentum of each object?
4. What factors other than mass contribute to an object's motion?
5. How does inertia relate to Newton's first law of motion?

**Tip:** Inertia is proportional to mass; understanding this concept can help with many physics problems involving motion.

Which object has the greatest inertia based on their masses and speeds?

Explore the concept of inertia and discover which object among A (4.0 kg, 6.0 m/s), B (6.0 kg, 5.0 m/s), C (8.0 kg, 3.0 m/s), and D (16.0 kg, 1.5 m/s) has the greatest inertia. This problem illustrates how mass affects inertia and includes insights into Newton's laws of motion.
