Practice Weight in Physics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The gravitational force acting on an object due to its mass, directed toward the center of a massive body.
How hard gravity pulls you toward the ground — it changes on different planets.
Example 1
easyWhat is the weight of a 12 \text{ kg} object on Earth? Use g = 9.8 \text{ m/s}^2.
Example 2
mediumAn object weighs 196 \text{ N} on Earth. What is its mass? Use g = 9.8 \text{ m/s}^2.
Example 3
hardA person weighs 686 \text{ N} on Earth (g = 9.8 \text{ m/s}^2). What would they weigh on Jupiter where g_J = 24.8 \text{ m/s}^2?
Example 4
easyA 15 \text{ kg} backpack is on Mars where g = 3.7 \text{ m/s}^2. What is its weight?
