by Ron Kurtus (updated 29 May 2023)

Take this Mini-Quiz to check your understanding of the lesson material.

1. If an object has a mass of 30 kg, what is its weight?

294 newtons

30 N

2. What is the weight of an object of 2 pounds mass?

2 pounds

12 newtons

64 lb-f

3. What is a reason many people don't use newtons for weight?

Because newtons denote mass

Some people just want to be different

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
