The Types of Forces
The types of forces are:
- Push
- Pull
- Twist
Friction
Friction is a contact force. It relies on the type of surface, the weight of the object and the surface area.
Friction can be useful or unwanted. This is shown below

Gravity
- Non - contact force
- Greater the mass, greater the gravity
- Gravity affects weight
Terminal Velocity
Terminal velocity means falling at a constant speed.
Weight (gravity force) = Air resistance
Weight (gravity force) = Air resistance

Inertia
Inertia has a tendency to resist change.

Stability
There is one more structure that provides stability, and that is called a truss. Click on the button below to check it out.
