Study Notes
Gravitational Forces
- Gravity is the force that causes objects to fall towards the Earth or other celestial bodies in space.
- It is a universal force that attracts two bodies with mass towards each other.
Planetary Orbits
- Gravitational force keeps planets in orbit around the sun.
- This force is crucial for maintaining the stability and structure of solar systems.
Matter in Objects
- The amount of matter in an object is called its mass.
- Mass is a measure of the substance contained within an object, typically expressed in grams or kilograms.
Weight and Location
- Weight is the gravitational force acting on an object and can change depending on location due to variations in gravitational pull.
- For instance, weight decreases on the Moon due to its weaker gravitational force compared to Earth.
Mass vs. Weight
- Mass and weight are not the same; mass is constant while weight varies based on gravitational forces.
- Mass remains unchanged regardless of location, while weight fluctuates based on the strength of gravity acting on that mass.
