Weight

Weight is a measure of the force of gravity acting on an object. It is different from mass, which is a measure of the amount of matter in an object. Weight is directly influenced by the gravitational pull on an object, so it can vary depending on the location in the universe. The standard unit of weight is the newton (N) in the International System of Units (SI) or the pound (lb) in the US customary system.

Key Points to Remember:

Weight is the force of gravity acting on an object.
It is different from mass, which is a measure of the amount of matter in an object.
The standard unit of weight is the newton (N) in the International System of Units (SI) or the pound (lb) in the US customary system.

Study Guide:

Here are some questions and activities to help you understand the concept of weight:

Questions:

What is weight?
How is weight different from mass?
What is the standard unit of weight?
How does weight change in different locations in the universe?

Activities:

Weigh different objects using a scale and record their weights in both newtons and pounds.
Research the weight of objects on different planets and compare them to their weight on Earth.
Discuss with your classmates how weight and mass are related and how they are different.

Concepts of Physical Science (SB1, SB2, SB3, SB4)

The student demonstrates an understanding of motions, forces, their characteristics, relationships, and effects by recognizing that objects can be moved without being touched (e.g., using magnets, falling objects, static electricity).

Concepts of Physical Science: A student should understand and be able to apply the concepts, models, theories, universal principles, and facts that explain the physical world. A student who meets the content standard should:

Develop an understanding of motions, forces, their characteristics and relationships, and natural forces and their effects.
