🌍 Gravity and Weight
This quiz explores gravity as a fundamental force that pulls all objects toward Earth. You'll learn to distinguish between mass and weight, understand how gravity affects motion and structures, and discover why gravity varies with location. Through real-world scenarios and calculations, discover why things fall and how gravity shapes our world. **What you'll learn:** - Gravity is a force that pulls objects toward Earth - The difference between mass and weight - How to calculate weight using the formula W = m × g - How gravity affects the motion of falling objects - How gravitational force varies with distance from Earth's center

- Question 4
If an object has a mass of 10 kg on Earth, and Earth's gravitational acceleration is approximately 10 m/s², what is the object's weight in newtons?
- Question 5
Weight is measured in kilograms.
- Question 6
Why do objects fall straight down toward Earth?
- Question 7
How does gravity change as you move farther from Earth's center?
- Question 8
An astronaut on the Moon weighs less than on Earth because the Moon has less mass than Earth.
- Question 9
Which scenario best describes the relationship between mass and weight?
- Question 10
What is the SI unit used to measure weight?
