Scientists use kilograms to indicate the mass of an object, and it is common for Americans to use pounds as a measure of weight. On Earth, the force that one kilogram of mass has on the bathroom scale is equal to 9.8 Newtons or a weight of 2.2 pounds.
This force of attraction between you and the Earth (or any other planet) is called your weight. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero.
LEARNING OBJECTIVES. Explain why, on Earth, we can only feel gravity pulling us down, and not sideways towards other objects. Explain how gravity influences the motion of planets in our solar system. Understand the usefulness of models as well as their limitations. CREDITS. Ben Finio, PhD, Science Buddies. Overview.
Students learn about gravity, mass, and weight by traveling through the solar system after a teacher led demonstration. Time: 45-60 minutes. Grade Level: 3-5, 6. Next Generation Science Standards: 5-PS2-1. Support an argument that the gravitational force exerted by Earth on objects is directed down. Utah Core Standards: SEED Standard 3.3.3.
Take a tour of the solar system to understand the relationship between gravity, mass, and wieght. Grades • 3-6 Next Generation Science Standards • 5-PS2-1. Support an argument that the gravitational force exerted by Earth on objects is directed down. Materials • A scale (or just guess your weight) • A lab sheet Utah Science Standards
However, you can build a model of our solar system that demonstrates the concept of gravity, using balls of different sizes to represent the sun and planets. Watch the summary video for an excellent introduction to the model.
Weight is the force of gravity acting on an object. Weight is a force and so it is measured in newtons, N. The force of gravity is not the same everywhere and so the weight of an object can...
