1. GRAVITY AND FORCE NOTES

2. Forces A push or a pull Contact – 2 objects touching
Non-contact – force applied without touching

3. Contact Forces
Applied force (one object directly pulls or pushes another)
Elastic force (force exerted by a compressed or stretched object)
Normal force (support force exerted on an object that touches another stable object)

4. Non-Contact Forces
Electric
Magnetic
Gravity

5. Gravity
A non-contact attractive force that exists between all objects that have mass
Based on mass and distance
As the mass of objects increases, gravitational force increases
As distance between masses increases, gravitational force decreases
