* Gravity: A fundamental force that attracts objects with mass towards each other.
* Mass: A measure of the amount of matter in an object.
* Weight: The force of gravity acting on an object's mass. It's measured in units of force, like Newtons (N).
Key Formulas:
* Weight (W) = Mass (m) x Acceleration due to gravity (g)
Where:
* g is the acceleration due to gravity, which is approximately 9.8 m/s² on Earth's surface.
Example:
A person with a mass of 70 kg would have a weight of:
* W = 70 kg x 9.8 m/s² = 686 N
Important Points:
* Weight is not the same as mass. Mass is an intrinsic property of an object, while weight depends on the gravitational field it's in.
* Weight varies depending on the gravitational field. For example, an object would weigh less on the Moon than on Earth because the Moon's gravitational field is weaker.
* The force of gravity increases with increasing mass. A more massive object will experience a stronger gravitational pull.
